You should be able to pick up everything locally, shops down the local ghetto tend to have everything, the staple ingredients I tend to use all the time are ghee, cumin, tumeric, garam marsala, cardomon, cinnamon, nutmeg, bay leaves (fresh ideally, chilli powder, paprika, coconut milk, fresh coconut, ginger garlic, chillis and onions.
I’ve recently started to a similar thing to the woman towards the end, I start by very lightly frying a few chopped carrots, an onion, ginger and 4-5 garlic cloves then take it out and coarsely blitz it, I then add it back into my wok after the coconut milk has gone in. Have also recently stopped frying/browning the meat first and basicly boiling it as the mixture reduces down, makes it more tender.
I started off with a recipe online and have tweaked it since adding things like sugar, honey and the carrots mentioned earlier, couldn’t go back to stuff out of a jar now. Had a lovely crevette curry for lunch yesterday. 🙂
