Brush with a little melted butter, if you like.

Cover the bowl and refrigerate the chicken for 2-3 hours or better overnight. Mix the chicken pieces with thick yogurt, coriander powder, Kashmiri red chili powder, ginger-garlic paste, garam masala powder, lime juice, and salt. For the mint yoghurt, pick the mint and pound to a paste in a pestle and mortar. Wash the chicken breasts and drain any extra water.Meanwhile, cook the chicken in a hot griddle pan on a high heat, until gnarly all over but still slightly pink in the middle.Stir in the fenugreek and 1 heaped tablespoon of your cashew paste and leave to simmer on a low heat for 5 minutes. Fry for 2 to 3 minutes, until golden and aromatic, then pour in the tomato sauce. Halve and deseed the green chillies, then place in a large clean pan on a medium-high heat with the butter.Add the chilli powder and cumin, cook for 1 minute more, then strain the tomato mixture through a coarse sieve set over a clean bowl. Cook for 15 minutes, breaking them up with the back of a wooden spoon, until they’ve cooked right down. Roughly chop the tomatoes and add to the pan with a good pinch of salt.Cook for 5 minutes, or until softened but not coloured. Now back to your sauce: peel and finely chop the onions and place in a large pan on a medium-high heat with 2 tablespoons of groundnut oil.Add a good pinch of salt, toss well and leave to pickle. For the onion pickle, peel and finely dice the onion, then place in a small bowl with 2 tablespoons of the vinegar.When you’re ready to cook your curry, drain the liquid then grind to a paste in a pestle and mortar (or use a powerful blender), adding a splash of milk to loosen, if needed. To get the first part of your sauce started, soak the cashews overnight, if using, in 150ml water.Pour it over the chicken, mix well and leave to marinate in the fridge overnight For the second marinade, stir the ground spices into the yoghurt and season with ½ teaspoon of salt.Add a pinch of sea salt and the chilli powder, and give it all a good rub and mix up. Peel the ginger and garlic and finely grate over the chicken. For the first marinade, put the chicken in a bowl and squeeze over the lemon juice.
