How to cook deliciously - Asian-style fish & chips

1 . Stage

In a large bowl, combine the miso paste with 1 tbsp rice wine vinegar and 1 tsp sugar. Put the cod fillets in the marinade and turn over so they are evenly coated. Cover with cling film and chill for 1 hr.

2 . Stage

Put the radishes in a small bowl with the black sesame seeds, the remaining vinegar and sugar, and a pinch of salt. Leave to pickle for at least 30 mins.

3 . Stage

For the wasabi tartare sauce, combine all the ingredients and season well. Set aside or chill in the fridge until needed.

4 . Stage

Meanwhile, put the sweet potato chips in a large saucepan filled with cold salted water. Bring to the boil and cook for 7-8 mins until slightly tender. Drain and leave to steam-dry for 2 mins.

5 . Stage

Fill a large saucepan with the oil until two-thirds full. Place over a medium-high heat until the oil reaches 180C on a temperature probe (or until a piece of bread crisps up in 20 secs). Meanwhile, make the tempura batter by combining the flours and gradually whisking in the soda water. Whisk until the batter is lump-free, then chill until needed.

6 . Stage

Once the oil has come to temperature, fry the sweet potato chips in batches until golden and cooked through, about 5 mins. Transfer to a baking sheet, season with salt and place in a low oven to keep warm while you fry the fish.

7 . Stage

Tip some seasoned flour onto a plate and dip the cod fillets in it, patting off any excess. Dip into the batter and fry in the same oil as the chips for 3-4 mins, until the batter is golden and the fish is cooked. Drain on kitchen paper.

8 . Stage

Serve the cod with the chips, wasabi tartare, pickled radishes and lime for squeezing over.
