Mix the garlic and ginger pastes, yogurt, spices and lemon juice with a little seasoning in a bowl until fully combined. Add the lamb chops and mix really well again, then cover and chill for 4 hours but preferably overnight.
Remove the lamb chops from the fridge 30 minutes before you’re ready to cook. Mix together everything for the salsa with some seasoning.
Heat a BBQ or griddle pan to hot. Scrape off the marinade from the lamb cutlets and season. Grill the cutlets for 1-2 minutes each side until really charred. Rest on a plate for 5 minutes. Serve with lemon wedges for squeezing, the salsa, roti or naan and a little seasoned yogurt.
