Char-grilled lamb with green chilli and sesame sauce

1.Preheat a char-grill pan over high heat and char-grill chillies, turning occasionally, until evenly blackened (8-10 minutes), transfer to a bowl, cover with plastic wrap and stand to steam (15 minutes). Peel chillies, remove seeds (discard skin and seeds), thinly slice and set aside.

2.Meanwhile, preheat oven to 180C. Spread nuts separately on two oven trays and roast, stirring occasionally, until browned (10-15 minutes for almonds, 8-10 minutes for hazelnuts), cool, then coarsely crush in a mortar and pestle and set aside.

3.Meanwhile, stir sesame seeds occasionally in a small frying pan over medium heat until golden (4-5 minutes), set aside to cool.

4.Combine chilli, nuts, sesame seeds, oil, vinegar, Aleppo pepper, tomato paste and garlic in a large bowl, season to taste with salt, mix to combine well, then stand until sauce changes colour and flavours develop (15-20 minutes).

5.Preheat a char-grill pan over high heat. Brush lamb lightly with oil, char-grill, turning once, until cooked to your liking (2-3 minutes each side), rest for 5 minutes, then serve hot, drizzled with green chilli and sesame sauce, scattered with spring onion.
