Aubergines with den miso

Years ago, before I'd even met Dr W, I had a boyfriend whose sister-in-law was Japanese. She and I didn't agree on much, but we did agree that these aubergines (which she made every time I visited her house) are pretty sublime.

Takako used to make this using those lovely wee Japanese aubergines - the sort that leave you gasping with their visual similarity to eggs and explain the whole eggplant nomenclature thing (not obvious when you are 18 and the only eggplants you have ever met are purple and shaped like a torpedo). Happily for those of us without a supplier of dear little Japanese aubergines, this works very well with the purple sort too. Aubergines are a wonderfully meaty sort of vegetable. Although this works really well as an accompaniment, this lovely meatiness means that you can happily serve this dish as the main event, with rice and perhaps a salad dressed with some rice vinegar. It's also a good win if you have an unexpected visiting veggie, and, being one of those things you serve at room temperature, I think it's really, really good as part of a picnic. These do soak up quite a lot of oil, as is common with aubergines, but hell - it's not like you're making this dish every day. To serve two, you'll need:

2 medium aubergines
200g shiromiso (white miso)
2 tablespoons sake (Chinese rice wine is good here if you have no sake)
2 tablespoons sugar
2 tablespoons mirin
6 tablespoons ground nut oil

As usual, if you're having trouble finding white miso, head for a large independent health food shop. They tend to have a bewilderingly good selection of miso, seaweeds, pickled ginger and the like. I have no idea why, given that most of the other nutty, protein-knitted, fermenty things masquerading as food that the health food shop I use sells are things I have no interest in ingesting at all. Boo hippies.

Start by slicing the aubergines into three lengthways. Slash the cut surfaces diagonally, without cutting all the way through the flesh, and without cutting the skin. Fry in the hot oil over a medium heat, turning halfway through, until the skin and flesh is golden brown, and the aubergine is soft.

While the aubergine slices are frying, make the den miso by combining the mirin, sugar, sake and miso in a small frying pan and bringing to a very gentle simmer, stirring all the time. Cook the sauce for two minutes and keep warm until the aubergines are cooked.

Move the cooked aubergines to a plate and smear the hot den miso all over their upper surface, making sure the paste gets into the slashes. Leave the slices to come down to room temperature before serving - for some reason, this dish is all the more delicious when it's cold.

Miso-glazed salmon

This Japanese way with fish requires you to think ahead by a couple of days. Once you've slathered it with its thick sauce, the salmon needs to cure and marinate in the fridge for at least 48 hours, by which time its flesh will be delicately infused with the flavours from the den miso. Once it's out of the fridge, it's simplicity itself to prepare under the grill.

Marinading fish in den miso is a delicious, traditional treatment. Japanese grocers in the UK often offer fish ready-smeared and packed under plastic for you to cook when you return home. A den miso marinade is also used in Nobu's utterly gorgeous black cod. I've never managed to find any black cod for sale, but salmon is just great here - try sea bass fillets too if you can get your hands on some.

To serve two, you'll need:

2 one-person-sized pieces of salmon fillet, skin still on
200g shiromiso (white miso)
2 tablespoons sake (Chinese rice wine is good here if you have no sake)
2 tablespoons sugar
2 tablespoons mirin

Most UK supermarkets seem to be stocking miso, sake and mirin (a sweet rice wine) these days, although the alcohols will be with the foreign foods section, not in the booze section. If your supermarket doesn't carry miso, have a look in your local health food shop. I've noticed that for some reason, they almost all sell a good variety of Japanese kelps, soya sauces, and miso.

Put the miso, sake, sugar and mirin in a bain marie and simmer the mixture (which is now den miso) over boiling water for 40 minutes, stirring occasionally, until the colour darkens. Remove the den miso from the heat and set aside to cool.

Put the salmon in a small bowl and pour over the cooled marinade, making sure everything is well-coated. Cover with cling film and leave in the fridge for between two and three days, turning the fish daily.

When you are ready to cook the salmon, lay it with the skin side down on a rack over tin foil. Grill under a high flame for about four minutes, until the miso is caramelising and bubbling as in the picture. Turn the fish so the skin side is uppermost and grill for another four minutes, watching carefully to make sure the fatty skin doesn't catch and burn.

The fish will be sweet and silky with a crisp and caramelised skin. Serve with rice and a green vegetable.
