I’d be happy just to eat all of the new-season’s asparagus steamed or grilled with some butter or some parmesan – maybe with some hollandaise, some truffle oil or a squirt of lemon juice. But every now and then it’s nice to gussy things up a bit, so here is a downright swanky way with one of my favourite vegetables.

Don’t be scared of either the filo pastry crust or the beurre blanc. Both can appear to be quite intimidating ingredients, but filo (which you can buy ready-made at the supermarket) is actually very, very easy to handle; and if you follow the instructions below you’ll find the beurre blanc a breeze to make.

To serve 4 as a main course or 6 as a starter you’ll need:

Croustade
10 sheets filo pastry
150g unsalted butter
700g asparagus
500g salmon, or a mixture of salmon and another firm white fish
1 teaspoon tarragon
2 shallots
Salt and pepper

Beurre blanc
225g unsalted butter, cold from the fridge
2 shallots, sliced
1 bay leaf
3 peppercorns
5 tablespoons white wine
1 tablespoon white wine vinegar or sherry vinegar
1 teaspoon creme fraiche
4 tablespoons snipped fresh chives
Salt and pepper

Start by infusing and reducing the wine and vinegar for your beurre blanc. In a small pan, combine the wine, vinegar, the sliced shallot, the bay and the peppercorns. Over a medium heat, reduce the contents of the pan until you have only a tablespoon of syrupy liquid left. Remove the pan from the heat, discard the bay and peppercorns, and reserve the shallots.

Preheat the oven to 180ºC (350ºF) and steam the fish for ten minutes.

While the oven is heating, assemble the croustade in a metal baking dish about the same size as a single sheet of filo. Melt the butter and brush the bottom of the dish with a layer, then place the first sheet of filo on the buttered surface. Brush the top of the filo sheet with butter, add another layer of filo and butter the top of that, until you have built a stack of five buttered sheets.

Flake the steamed fish into pieces and chop the asparagus spears (discarding the woody ends) into pieces about the length of your thumb. Scatter the fish flakes and the asparagus over the filo. Dice the shallots from the beurre blanc mixture with the fresh shallots, and scatter those over too, along with a little salt, plenty of pepper and the tarragon.

Layer the remaining five pieces of filo, buttering each one as you go, over the top of the asparagus mixture. Use a knife to score the top sheets gently into squares in the size you want for serving. Put the croustade in the oven and bake for 35-40 minutes, until the top is crisp and a dark gold colour.

About 15 minutes before the croustade is ready to come out of the oven, make up the beurre blanc. Chop the cold butter into pieces about the size of the top joint of your thumb (there are lots of finger measurements in today’s recipe). Stir the creme fraiche into the wine and vinegar reduction you set aside earlier, and put it over a medium heat.

Drop three of the butter pieces into the reduction, and whisk until they are half-melted. Drop another three in and continue to whisk until the original three pieces have melted completely, then add another three. Continue to add the butter pieces three at a time, whisking hard, as the ones you have put in before melt, until the butter is all incorporated. Remove from the heat and stir through most of the chives, reserving two teaspoons to garnish. Taste for seasoning, adding extra salt and pepper or a little lemon juice if you think it needs it.

Use a sharp-edged spatula to divide up the croustade along the marks you made earlier, and spoon some of the beurre blanc over each serving with a little sprinkle of chives. Serve immediately.

Goat’s cheese and asparagus tart

Asparagus tart

I kind of wish that supermarkets wouldn’t sell asparagus out of season – we’re all familiar with the tasteless, slightly limp kind whose sugars have long turned into starch, because the spears themselves have been bussed in from South America. Nothing’s going to taste good after that long in a cargo hold. It’s enough to make you forget just how good a sweet, fresh English stem of the stuff can be. The English season is short, but it’s worth ignoring asparagus for the rest of the year and waiting for early May. From now on, we’ll have about eight weeks of tender local asparagus in the shops.

I’ve got two great asparagus recipes for you this week. This tart is a doozy; it takes advantage of the lovely affinity between asparagus and goat’s cheese, and can be served hot or cold. I haven’t called it a quiche because I know some of you are squeamish about quiches…

To make one 20cm tart, you’ll need:

Shortcrust pastry – either buy a pre-made roll or make your own with:
175g flour
50g butter
25g lard
A little water

Filling
3 banana shallots
50g pancetta cubes
200g fresh English asparagus spears
120ml creme fraiche
3 eggs
1 heaped teaspoon thyme leaves
200g goats cheese log (I used Neal’s Yard Ragstone, which is pretty strong – for a milder flavour use a younger cheese)
1 tablespoon butter
salt and pepper

Asparagus tart

If you are making your own pastry, rub the fats into the flour with your fingertips until the mixture resembles breadcrumbs, and add just enough water to make everything come together into a ball. Wrap in cling film and refrigerate for 30 minutes. Roll out on a floured surface.

Use the pastry to line your 20cm tart dish, and pop the whole thing in the freezer to firm up for 30 minutes while the oven heats up to 200ºC (390ºF). While the pastry is chilling, fry the finely chopped shallots with the pancetta cubes in the butter, until the shallots are golden.

When the pastry has had 30 minutes in the freezer, prick the bottom a few times with a fork, line the base with greaseproof paper, pour in some baking beans to hold everything down, and blind bake (this is just a way of saying part-bake; you’re doing this so that the crust is crisp and cooked) for 20 minutes.

Remove the tart case from the oven and turn the temperature down to 180ºC (350ºF).

Arrange the raw asparagus spears, chopped into pieces, to cover the bottom of the pastry case. Sprinkle over the pancetta and shallot mixture with the thyme. Use a fork to beat together the eggs and crème fraîche with half a teaspoon of salt and plenty of black pepper until smooth, and pour the egg mixture into the case. Finally, slice your cheese log into ½ cm pieces and lay them on the top of the tart.

Bake in the cooler oven for 30-40 minutes, until the filling has set and the top is golden. Serve hot or cold.

Prawn and asparagus risotto

As a contrast to the budget-conscious meals I’ve been writing about recently, I decided to shove the boat out and make something with a bit of pre-Christmas luxury. Prawns, asparagus, saffron and salty, savoury pancetta cubes don’t come cheap, but if you mix them all together in a boozy risotto like this they’re delicious beyond all reason – worth every penny.

There are a few different kinds of risotto rice available in shops. I always use Carnaroli, which can be less easy to find than the more common Arborio. It’s worth hunting some down. Carnaroli rice has a slightly longer, slimmer grain than Arborio, and has a higher starch content and firmer texture when finished; you can hold a risotto made with Carnaroli rice at the al dente stage without worrying about the grain collapsing into a sandy sludge as Arborio might. That extra starch makes a world of difference in a risotto, resulting in a really velvety, creamy finish that you just don’t get with other rices. Carnaroli is still grown in the Po valley, where a network of canals constructed in the 19th century irrigates the rice terraces with water from the Alps. American readers can find Carnaroli produced in South America, but the Italian product, raised in the traditional way, is supposed to be the finest, and is really worth hunting down.

To serve four, you’ll need:

320g Carnaroli rice
1 litre fish or chicken stock
1 large glass white wine
2 banana shallots
3 stalks celery
4 cloves garlic
100g pancetta cubes
a few sprigs of thyme
2 teaspoons fennel seeds, ground coarsely in a mortar and pestle
1 large pinch saffron
1 large pinch chilli flakes
180g raw, shelled prawns
150g asparagus tips
1 large handful grated parmesan
1 handful chopped parsley
40g butter
2 teaspoons olive oil

Put the saffron in an eggcup and pour over boiling water. Bodge the saffron around in the water with a teaspoon, and set aside while you prepare the other ingredients.

Chop the shallots, garlic and celery finely. Sauté the pancetta in a teaspoon of olive oil in a large, heavy-based pan over a high heat for about five minutes until its fat is running, then add the butter, shallots and celery to the pan with the fennel, reducing the heat to medium. Sauté, keeping everything on the move, for two minutes, then add the dry rice to the pan, and continue to sauté until any liquid from the vegetables has started to absorb into the rice. Pour the glass of wine and the contents of the saffron eggcup into the pan and stir until it is absorbed. Add a ladleful of the hot stock to the rice and bring, stirring, to a gentle simmer. As the stock is absorbed, add another ladleful while you stir. Continue like this for about 18 minutes, stirring and adding gradually to the liquid in the pan, until the rice is soft, tender to the bite and velvety.

When the rice is nearly ready, saute the prawns in a a teaspoon of olive oil with a pinch of chilli flakes until they turn pink, and chop the asparagus tips into bite-sized pieces. Stir the asparagus into the hot risotto for two minutes. The heat from the rice will cook them to a bright green. Immediately before serving stir the prawns (with any juices and the butter from the pan) and parmesan into the mixture with salt to taste (you shouldn’t need much, depending on the saltiness of your pancetta and stock) and a handful of chopped parsley.

Roast asparagus with shaved parmesan

If you thought the hollandaise sauce recipe from the other day sounded like too much hard work, this asparagus recipe will suit you down to the ground. It’s very quick and easy, and this cooking method makes the most of the tender sweetness of the stems. It also looks posh, so you can serve it up as a starter (or as an accompaniment) to guests and feel smug when they congratulate you on something which, in reality, only took you five minutes to put together.

For a starter, look at serving between six and eight stalks of asparagus per person. You can get away with less than this if you’re making it to accompany something else as a main course, but it’s worth making plenty because roast asparagus is downright delicious.

To serve two as a starter you’ll need:

16 stalks of asparagus, as fresh as possible
½ teaspoon flaked Italian chilli peppers
Zest of a lemon
3 tablespoons extra virgin olive oil
50g parmesan cheese
Salt (preferably something crystalline, like Maldon) and pepper

Preheat the oven to 180° C (350° F).

Snap the bottoms off the stems of asparagus. They’ll come apart naturally, with a lovely snapping sound, at the point where the woody part (which you don’t want to eat) begins. Arrange them in a single layer in a baking dish.

Sprinkle the flaked chilli and lemon zest over the asparagus, and drizzle with the olive oil. Roast the asparagus in the oven for 10-15 minutes until bright green.

While the asparagus is roasting, use a potato peeler to shave the parmesan into little pieces. As soon as the asparagus comes out of the oven, scatter over the parmesan, which should soften a little as it meets the hot asparagus. Serve the roast asparagus with crusty bread if you’re eating it as a starter.

Asparagus with hollandaise sauce

Isn’t eating at this time of year brilliant? The rhubarb is still sprouting away, and now the asparagus is shooting up as well. If you live in Cambridgeshire, it’s well worth making a trip to Burwash Manor Barns in Barton, just outside Cambridge, where they grow tonnes of the stuff. It’s picked fresh daily and sold on-site at the Larder (a very nice deli), where you’ll find a lady outside trimming the stems of an enormous heap of asparagus fresh from the fields, and packing it in wrappers for sale. If you cook it as soon as you get home so the sugars don’t have a chance to turn into starch, you’ll find it amazingly sweet. Supermarket (and, sadly, market) asparagus is never available this fresh.

English asparagus is a real delicacy. Unlike asparagus grown in hotter climates, it pops up out of the ground relatively slowly, allowing the plant to build up a much greater concentration of sugars. Burwash asparagus is available as Class I and Class II (50p cheaper than the Class I this year) – I’d recommend the Class II packs, which taste exactly the same as the Class I asparagus, but contain spears which are a bit bendier than the ruler-straight Class I. (See picture for extent of bendiness.) The thickness of spear you choose is entirely a matter of personal taste, but do make sure that all the asparagus that you steam is the same thickness, or else it won’t cook evenly.

Of course, dressing your asparagus with melted butter or just dipping each spear into the yolk of a soft-boiled egg makes for a perfectly delicious starter. That said, dressing them with a hollandaise sauce – essentially just butter and yolks with an acidic spike of reduced vinegar – somehow works out to be about ten times as delicious as either butter or yolk on their own.

Hollandaise sauce is a rich emulsification of butter and good vinegar (or lemon juice in some recipes), held together by egg yolks. I always add a little boiling water to loosen the sauce and prevent it from becoming too solid – a very thick hollandaise can be overpoweringly rich.

Making hollandaise isn’t as intimidating or difficult as some make out, but it will need your full attention, so you need to make sure the answering machine gets any phone calls and ignore any cries of ‘I can’t find my shoes!’ from the family for the ten minutes or so it takes to make.

Hollandaise is cooked at a very, very low heat. In order to stop the yolks from getting too hot and turning into an omelette, you’ll be making the sauce in a bain marie or double boiler. I don’t own one of the expensive dedicated double boilers – sitting a mixing bowl on the rim of a pan part-filled with simmering water works just fine and doesn’t take up any extra precious cupboard space. To dress asparagus for four, you’ll need:

2 egg yolks
2 tablespoons boiling water
3 tablespoons good white wine vinegar (I used Maille, which, for no very good reason, keeps turning up at my local branch of TK Maxx.)
225g (half a pat) good butter
2 peppercorns
1 bay leaf
Salt to taste

The quality of your butter is all-important here. I used Bridel from Normandy. Bridel or Beurre d’Isigny is fantastic here because of its rounded and smooth flavour.

Make sure the water for steaming the asparagus is ready and boiling on the hob as you make the sauce – you’ll need a couple of spoonfuls of it for the hollandaise. Throw the asparagus into the water and put the lid on as you start to whisk the butter into the hollandaise – it only wants a little cooking, and should be bright green and ready when you finish the sauce.

Put the vinegar in a small pan with the peppercorns and bay leaf, and simmer it gently until it has reduced to about a tablespoon-full. Remove from the heat but keep warm. Melt the butter and put it in a warm jug.

Place a mixing bowl on top of a saucepan part-filled with water. The water should not touch the bowl. Bring the water to a simmer while beating the egg yolks vigorously with a hand whisk in the bowl. As the bowl warms, you will notice that the yolks start to thicken. Add a tablespoon of the boiling water to the yolks and continue beating until they begin to thicken again. Add another tablespoon and beat until the yolks are thickening once more, then add the vinegar with the bay and peppercorns removed, beating all the time until the sauce starts to thicken up again.

Pour the butter into the egg mixture in a very thin stream (as if you were making mayonnaise). Continue to whisk as you pour until all the butter is amalgamated, then remove the bowl from the heat. Taste for saltiness and acidity. If you want a little more bite to the sauce, squeeze in a few drops of lemon juice. Remove the asparagus from its water and serve with the sauce either drizzled over or as a dip.

Hollandaise sauce freezes well – when you want to use it, just bring it back to room temperature slowly.
