We had roast pork yesterday, and tonight we're having roast pork curry.
If you can, marinade the pork first in yoghurt, paprika, coriander (ground), cumin, turmeric, and chilli powder.
LOTS of onions and garlic with garam masala, some fresh ginger if you have it, and some more of the herbs that went into the marinade.
Then add the pork, and add mushrooms, peppers, chillies and fresh tomatoes. THen add a tin of chopped tomatoes.
Usually the consistency is fine - if you like a more saucy curry, feel free to augment with a jar or Patak's/Sharwoods.
If you want to add more veg, then frozen chopped spinach works really well (as does fresh, but it's much pricier) and you can add peas 5 minutes before you serve.
ideally add a bunch of fresh chopped coriander.
Serve with rice and naan, and if you like, homemade raitha is dead easy to make. (Chopped cucumber, one clove of garlic, a teaspoon of mint sauce and a load of yoghurt).
