Put the onion garlic and ginger in a food processor and blitz until you get a fine and even chop
Add a drizzle of olive oil to a pan and cook this mix on a low heat
Meanwhile add your cumin, caraway and coriander seeds to a dry frying pan to release the flavours and then grind. If your sprices are already ground you can skip this step
Once ground add the tumeric and chilli powder to the spices
Your onions, garlic and ginger will fry for roughly 30 minute. Jamie says to mix through three or four times but I mix more often
After the first 5 minutes put a lid on the pan. Jamie says to take the lid off for the last 10 mins to reduce the liquid but I don’t find I have any liquid to reduce
Add the passata and the first group of spices then mix thoroughly. I add 200g more Passat than Jamie
Stick a lid on it and leave it to cook for another 10 minutes
Meanwhile I ground some fenugreek seeds and added it to the pan with the garam masala
10 mins out from serving add your king prawns to the hot sauce and cook gently for 10 minutes or until cooked thoroughly. I made my sauce earlier in the day and reheated it once we were ready to cook
I served our curry with a brown rice, cauliflower and garlic side which makes a great leftovers lunch the next day. And I make my own flatbreads which are in someways the star of the show!
