Crisp skate with onion rings, parsley and curry rémoulade

1.Bring skate wings, vinegar, thyme, garlic, 1 tsp sea salt and 2.5 litres cold water to the boil in a large saucepan over medium-high heat, reduce heat to low and simmer until skate is just cooked through (8-12 minutes). Drain, remove skin, carefully remove flesh from cartilage (discard skin and cartilage), break into large pieces and cool. Transfer to a non-reactive container with lemon juice and olive oil and refrigerate to marinate (2 hours).

2.Meanwhile, for curry rémoulade, process yolks and lemon juice in a food processor to combine. With motor running, gradually add oil, starting with a few drops at a time, then in a thin steady stream, and process until thick and emulsified. Add curry powder, season to taste and set aside.

3.Place flour in a bowl, season to taste, whisk in butter and 240ml lukewarm water, then fold in eggwhite.

4.Preheat oil in a deep saucepan to 170C. Drain marinade from skate (discard), dip skate in batter and deep-fry in batches until golden and warmed through (3-5 minutes; be careful as hot oil will spit). Drain on absorbent paper. Dip onion rings in batter, deep-fry in batches until golden and crisp (3-5 minutes) and drain on absorbent paper. Deep-fry parsley until crisp (15-30 seconds) and drain on absorbent paper. Serve skate and onion rings hot, scattered with parsley, with curry rémoulade and lemon wedges.
