Nathan’s top tips on buying & cooking fish:

Use your senses

Check fish scales are intact. If they are coming off, the fish may have been over-handled. Look for shiny fish with bright eyes, not cloudy or glazed over. Fresh fish will have that lovely smell of the sea. If there’s a fishy, unpleasant odour that means it’s old. Flat fish, such as plaice or Dover sole, may feel slimy but this is a good sign that it’s fresh. Wash it with cold water before cooking.

Steamed fish

Steam fish for a health boost

The best way to cook fresh fish is by steaming it. It’s a low fat cooking method and means you keep all the nutrients in the cooking juices.

Use tin foil to make a little bag for a 150g piece of white fish (cod, pollock, haddock or hake). Add liquid (fish stock or wine), then seal it up, put it into hot oven and it will steam in about 5 or 6 minutes. It can sit and rest in its bag while you get everything ready.

Check frozen fish is sustainable

One benefit of frozen fish is that it's frozen at sea, so it’s really fresh, but you need to find sustainable versions. Look an eco-label such as those of MCS (Marine Conservation Society) or the Aquaculture Stewardship Council for farmed fish.

Oily fish

Holy Mackerel!

For me, the best way to get my weekly dose of oily fish is by grilling mackerel – it’s my favourite fish. Ask your fishmonger to fillet it. Rub a bit of olive oil on the dry fish, then grill for around 2 minutes on each side. Simple!

One fish, 2 meals

It’s better to buy less, buy quality and do more with it. I like to make Asian fish soup from the scraps. Even if the Waitrose fishmonger fillets a fish for you, you can ask to keep the head and bones. Simmer these for half an hour with water, shallots and chilli. Add noodles, veg and pieces of frozen fish for a flavourful meal.

Simple sauces

A well-matched sauce is all that's required to create the perfect fish supper

Romesco sauce

Pair with chunky white fish such as pollack. Serves 4; takes 40 minutes.

Preheat the oven to 200˚C, gas mark 6. Put 2 halved, deseeded red peppers, 4 halved tomatoes and 1 garlic bulb with the top sliced off on a foil-lined roasting tray. Drizzle with 1 tbsp olive oil, season, and roast for 30 minutes. Toss 30g crustless, torn white bread with ½ tbsp olive oil and put on another tray with 20g blanched hazelnuts and 20g blanched almonds; roast for 10 minutes. Take both trays out of the oven and set aside to cool. Remove and discard the skin from the peppers and tomatoes. Blitz the nuts in a food processor until roughly chopped; add the tomato and pepper, bread, 2 tbsp extra virgin olive oil and 1 tbsp red wine vinegar. Squeeze in the garlic cloves, discarding the skin; blitz to a smooth sauce. 

Salsa verde

Its sharpness cuts through oily fish. Serves 2; takes 5 minutes. Mix 1 chopped shallot with 1 tbsp rinsed and chopped capers, ½ x 25g pack flat leaf parsley, chopped, ½ x 25g pack basil, chopped, 1 crushed garlic clove, the zest and juice of ½ lemon and 2 tbsp olive oil

Caper butter

A great accompaniment for delicate white fish such as ray wings. Serves 2; takes 5 minutes. Melt 40g unsalted butter in a pan. When foaming, add 1 tbsp rinsed salted capers and squeeze in the juice of ½ lemon. Cook for 1 minute, until the butter is golden and smells nutty.

Light tartare sauce

A lighter version of a classic that works well with all fish. Serves 4; takes 5 minutes. Mix 125g half-fat crème fraîche with 2 tsp capers, 2 chopped cornichons, the juice of ½ lemon and 1 tbsp chopped flat leaf parsley.

Add just a drop or two to oysters for a fiery kick.
