Step 1

Mix the marinade ingredients together in a large bowl, add the diced lamb and stir to coat thoroughly. Marinate for 10 minutes (if that’s all you’ve got) or up to 2 hours if you have the time. (If marinating for more than 10 minutes, cover and return to the fridge.)

Step 2

Preheat your oven to 160C / 140C fan / gas mark 3 / 325F.

Step 3

Place the oil, onions and red pepper in a large, wide saucepan or large frying pan and cook gently with the lid on for 5 minutes or until softened. Turn the heat up and add the lamb (including all of the marinade), passata, coconut milk and ground almonds (optional), and bring to the boil.

Step 4

Put a lid on the pan and place in your preheated oven, if using an ovenproof saucepan. (If your saucepan is not ovenproof, transfer the curry to an ovenproof dish with a lid and then place in the oven.) Cook the curry in the oven for 1 hour 15 minutes.

Step 5

Remove from the oven and stir in the remaining garam masala and fresh coriander (cilantro).

Step 6

Serve with rice and/or naan bread.
