i learned to make this in aberdeen, from my flatmate hamidur salim laskar, who learned it from his mother.

here is approximately what you might need to prepare this dish:
a large pot (with lid, or improvised cover)

garlic, 1 to 3 cloves
onion, 1 large or 2 medium
turmeric, 1 to 1 1/2 teaspoon
coriander, 1/2 teaspoon
cumin, 1/2 teaspoon
curry powder, 1 to 1 1/2 teaspoon
plain yogurt (not low fat, not sweetened, not vanilla) 1 cup or more

add diced tomatoes, stir, put lid back on
wait a minute or three and add coriander, cumin, curry powder, stir, put lid back on
check every few minutes and if it starts to stick, add some water and stir well, if it still sticks, turn it down a bit
