Asparagus and salmon croustade with chive beurre blanc

Asparagus and salmon croustade

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.

Samphire, scallops and black pudding

The samphire season has just begun, and with this in mind, we drove up to Norfolk at the weekend with a coolbag to try to find some at a fishmonger. Unfortunately, it being a Bank Holiday, everybody else and his mother had also driven up to Norfolk. The fishmongers were empty of anything you’d have fancied eating, as if picked over by piscine locusts, and every seaside town we encountered was so full of people that we gave up and decided to go for a hike into the bleak salt marshes near Stiffkey (pronounced ‘Stooky’) to get away from everybody. Picnic backpack hoisted aloft, legs encased in waterproof boots, we walked out about three miles until we found the perfect spot by one of the causeway bridges that punctuate the saltmarshes – flowing, salty water running through a sticky clay bed. This is perfect samphire territory, and sure enough, there were beds and beds of the stuff growing along the water margin. I scrambled down into the water, offering up a prayer to the makers of Gore-Tex, and picked enough, roots and all, to fill both our picnic napkins.

Samphire is a glasswort, sometimes called sea-asparagus. (See the picture below for a bowl of raw, cleaned samphire.) There are a few different plants which are called samphire – we’re after the best-tasting variety, marsh samphire, which is a spectacular bright green, and grows in salty mud. The samphire Shakespeare mentions in King Lear was probably rock samphire, which is comparatively bitter. Marsh samphire has an assertively salty flavour reminiscent of oysters, and is tender enough to be eaten raw in a salad. (Dr W and I found ourselves snacking on it raw as I picked, straight out of the mud.) At this time of year, the samphire is young and tender – aim to collect shoots about the length of your forefinger, roots and all. Wrap them in a damp cloth and they’ll keep nicely in the fridge for a few days. To prepare, just rinse carefully in cold water from the tap and snip the roots off with scissors. Older samphire may be a bit twiggy – use your judgement, and snip off anything that’s not a tender tip.

If foraging’s not your thing, Tig (who is extraordinarily good value on the subject of seaweed and other salty things) mentioned in the comments of an earlier sea-vegetable post that the Fish Society will send mail-order samphire to you, in season.

Samphire’s at its absolute best with shellfish, so I grabbed a bag of tiny, sweet queen scallops from the supermarket and came up with this dish, which makes the most of the odd affinity pork has with scallops and samphire, sets them on delicious crisp discs, and marries the lot up with a beurre blanc flavoured with dill and Pernod. This looks and tastes most impressive, and while it’s a bit of a faff to put together, it’ll go down a storm at a dinner party, or served to people you love for a special occasion. To serve four as a starter or two as a main course, you’ll need:

150g cleaned marsh samphire
200g queen scallops
4 slices white multigrain bread
150g slim black pudding (if you can only find the pre-sliced kind, buy 12 slices)
3 fat, juicy cloves garlic
100g salted butter, plus another 225g salted butter for the beurre blanc
1 shallot
1 bay leaf
3 peppercorns
3 tablespoons white wine
2 tablespoons Pernod
1 tablespoon white wine vinegar
1 teaspoon double cream
2 tablespoons freshly chopped dill

Preheat the oven to 220°C while you chop the garlic finely, and cook it in 100g of butter until it is a very pale gold. Remove the garlic from the heat. Remove the crusts from the bread and use a rolling pin to roll the slices of bread until they are squashed flat, then use a round cookie cutter to make three circles out of each slice. Dip the twelve rounds in the garlic butter, lay on a baking sheet and cook on the top shelf of the oven for 8 minutes, until golden brown. Put on racks to cool.

Cut the black pudding into 12 rounds, leaving the skin on for now. Fry it over a medium heat in the remaining garlic butter for about 5 minutes per side, until the outsides are crisp. Peel off the skin and keep the little rounds of sausage on a plate in a warm place while you prepare the rest of the ingredients.

To make the beurre blanc, put the wine, Pernod and vinegar in a heavy-bottomed saucepan with the sliced shallot, the bay leaf and the peppercorns. Bring to a simmer and reduce until there are only two tablespoons of liquid left. Sieve the liquid to remove the shallot, bay and peppercorns, and return to the pan off the heat. Get the butter out of the fridge and cut it into cubes about the size of the top joint of your thumb.

Put the pan back over a low flame. Add a teaspoon of cream to the wine reduction and use a whisk to incorporate it into the liquid. (As I’ve mentioned in previous beurre blanc recipes, this addition of cream is cheating, but it does mean that your sauce won’t split.) Whisking vigorously, add the butter to the pan, three cubes at a time. When they are half-melted, add another three, still whisking hard. Repeat until all the butter is incorporated and remove from the heat.

When the beurre blanc is nearly ready, bring the remaining garlic butter and fat from the black pudding to a frying temperature and fry off the scallops for two minutes, until they are coloured and just barely cooked. Steam the samphire for four minutes.

To assemble the dish, make a little bed of steamed samphire on each plate, and put three discs of bread crisp on top. Put a slice of black pudding on each of these, pile the tiny scallops into the middle of the plate, and spoon over a generous amount of the beurre blanc. Serve immediately.

Paper-baked trout with beurre blanc

Talking food on the phone with my Mum last week, the subject got on to sauces. It turns out that we share a favourite – beurre blanc, a deliciously fatsome emulsion of melted butter suspended in reduced wine infused with herbs and shallot. After putting the phone down, I headed straight for the fridge.

Being fatsome, beurre blanc works best as a sauce for very lean dishes. I steamed trout en papilotte – inside a little bag made from greaseproof paper – in the oven, with more herbs and wine, then spooned the beurre blanc all over it. (I also spooned beurre blanc all over some home-fried potatoes, which are not pictured because only people who do not fear imminent death via clogged arteries should eat beurre blanc spooned all over home-fried potatoes.) It was ludicrously good.

To serve four, you’ll need:

Trout
Eight trout fillets
4 bay leaves
4 sprigs tarragon
4 sprigs parsley
4 thin slices of lemon (with skin)
2 shallots
White wine
Salt and pepper

Beurre blanc
225g unsalted butter
1 shallot
1 bay leaf
3 peppercorns
5 tablespoons white wine
1 tablespoon white wine vinegar
1 teaspoon double cream
Salt and pepper

Make sure the butter is chilled, and preheat the oven to 180° C (350° F).

Cut out four large squares of greaseproof paper and four squares of tinfoil. Lay the pieces of greaseproof on top of the tinfoil squares, and lay a bayleaf, half a sliced shallot, a slice of lemon and a sprig of parsley and tarragon in the middle of each. Place two fillets of trout on top of each pile of herbs and sprinkle with salt and pepper. Sprinkle a couple of tablespoons of wine over the fish and fold the paper and tinfoil over to create a little packet, sealing it tight with the foil. There should be a bit of room for the steam to circulate in each packet, so don’t wrap the fish up too tight. Put all four little packets on a baking sheet and put in the oven for 20 minutes.

As soon as the fish goes in the oven, start making the sauce. Put the wine and vinegar in a heavy-bottomed saucepan with the sliced shallot, the bay leaf and the peppercorns. Bring to a simmer and reduce until there is only 2 tablespoons of liquid left. Sieve the liquid to remove the shallot, bay and peppercorns, and return to the pan off the heat. Get the butter out of the fridge and cut it into cubes about the size of the top joint of your thumb.

Lower the heat, and put the pan back over the low flame. Add a teaspoon of cream to the wine reduction and use a whisk to incorporate it into the liquid. (A note here – adding cream is, strictly speaking, cheating. The cream stabilises the emulsion and will stop your sauce from breaking and splitting. Proper chefs will scoff and tell you that the addition of cream means your sauce is no longer a beurre blanc. Scoff right back at them, but make sure you take your time over it so that by the time they return to their own, cream-free beurre blanc pans, their own sauce will have split.) Whisking vigorously, add the butter to the pan, three cubes at a time. When they are half-melted, add another three, still whisking hard. Repeat until all the butter is incorporated and remove from the heat. Taste for seasoning and add salt and pepper.

The fish should be ready at around the same time you finish the sauce; if the timer goes before you’ve finished the sauce, don’t worry about it. The fish won’t mind an extra five minutes in the oven.

Some people like to open the little parcels of fish at the table – the burst of fragrant steam from the punctured parcel is a fantastic opening to the meal. Spoon over the beurre blanc and some fresh parsley, and serve plenty of new potatoes or mash to help you soak up all the delicious sauce.
