Its true, casseroles and curries taste even better the next day; their flavour mellows beautifully. This lamb curry is certainly one to do ahead, add the spinach when you reheat it.
A casserole will keep for up to 2 to 3 days in the refrigerator. Casseroles should be refrigerated immediately after the steam from cooking has evaporated. Place the hot casserole into a shallow container in the fridge so it cools quickly. Do not leave it to cool completely on the bench. To serve bring it slowly to the boil over a medium heat, reduce heat and simmer for about 3 minutes, or until the meat and sauce are both thoroughly hot.
Don’t rush the initial stage of browning the meat. This will make this dish rich in colour and flavour. Brown the meat in small batches over a medium-high heat.
Simmer the casserole gently and taste it to see if it’s ready. Stir occasionally and adjust the heat as it cooks if needed. When it’s done the meat should be tender enough to fall apart easily with a fork.
