chickpea, potato, spinach curry:
fried finely chopped onions in hot sunflower oil or similar for 15 mins until caramelised. Add green peppers if desired.
Separately, blanch roughly chopped waxy potatoes (skin on or off, your choice, i keep them on, DH takes them off) for about 5 mins just to take the hardness off, drain then add to the onions. Fry on a lowe heat for about 5 mins, stirring to avoid sticking.
Add 2-3 tablespoons of Pataks paste, such as rogan josh, for milder, vindaloo for stronger, fry further for about 2-3 mins to get spices going, then add tin of chickpeas (or pre-soaked chickpeas if not lazy!)
Then, there are some variations on the next bit
either - add tin of tomatoes, chopped and a little stock, simmerfor 20 mins, stirring occasionally to stop burning. Depending on how liquidy you want it, add a little more stock as it cooks.
or - add a little milk, to give it a deeper less tomatoey flavour, simmer gently, adding a little more milk as required. I like this way as I like it dry, hot and spicey, and this brings out the flavours well I think, but if you prefer tomato based, the above is more conventional.
once potatoes are cooked (20 mins or so), add several large handfuls of fresh spinach, large dollop of yoghurt, turn of heat and cover for 5 mins while you set the table. Or while you eat popadum with pickles.
Serve with steaming basmati rice (with saffron if feeling extravangant), chapati, and dhaal (will post seperately for ease)
