Garlic, crushed coriander seed, lashings of cumin. Black pepper if need be, or even cayenne. Flash fried before meat is added. Ginger / lemongrass if you want to go a bit more aromatic...
That's the basis of it all.
Usually, some onions. Very often some meat, sometimes chicken, sometimes beef. Goat is nice, when you can find it.
I personally adore lamb, but the other half is less keen. Occasionally, fish, or prawns.
Mushrooms, tomato or chickpeas don't kill it, exactly, but they aren't really necessary. Or, in my view, desirable. I love ladies fingers though. It's one of the few parts of them that I adore.
Sometimes we serve it all mixed up with boiled or fried rice. And with fresh coriander on top.
