Preheat the oven to 130°C fan bake or 150°C conventional bake.

Heat a little oil in a large heavy-based frying pan over a very high heat.

Pat the lamb dry with a paper towel, trim any fat and season with a little salt and pepper.

Add 2-3 chops to the pan and cook until browned on one side. Turn over and cook for another few minutes.

Transfer to a warmed plate and repeat with the remaining chops.

Discard any fat from the pan and return to a medium heat.

Add a little oil and the garlic, onion, anchovies, oregano and rosemary. Cook for 7-10 minutes until the onion is soft.

Add the tomato paste, tinned tomatoes, chilli powder (if using), stock and sugar. Stir to combine and nestle the chops in so they’re covered. Bring to a boil then turn off the heat straight away.

If your pan is ovenproof, cover and cook in the oven for 3 hours. If not, transfer everything to a covered casserole dish before placing in the oven.

With 15 minutes remaining, add the olives and capers (if using).

Remove from the oven, stir, and then check the seasoning. If the sauce seems a little thin, remove the lamb then simmer rapidly in an uncovered saucepan for 5-10 minutes to thicken it.
