Curry Base Recipe
This is adapted from curryhouse.co.uk, I would recommend this ebook to anyone, well worth the money.
Add remaining spiced oil (usually ~250ml) and top up with ground nut oil to ~500ml
Heat to medium and add 350gms of finely chopped onion
The oil will pretty much cover the onions, deep fry for about 10 minutes
Add 3 gloves of garlic chopped and 2 x 3mm slices of fresh ginger peeled and chopped, fry for a further 1 minute and then turn down and simmer for 10-15 minutes.
Take off the heat and allow to cool, add 350ml of water to a blender, add the oil and onion mixture to this and blend to a very smooth puree.
Add this back to the pot and add 45ml pasata, 0.5 tsp cumin, 0.5 TSP coriander, 0.5 TSP turmeric, 0.5 TSP salt, 0.25 TSP black pepper, add any previous remaining base you have, bring to the boil then simmer for 30 mins to 1 hour. (basically as long as it takes to get the oil to float so you skim it all off) skim off any froth that appears
Take off the heat and skim off the oil, dont worry about getting a bit of the base in as well as the oil, to my mind the most important thing is to get all the oil off.
As you can see when finished using a batch of base you should always make sure you have spiced oil left over and some base (~300ml) left over to make the next batch.
I will post the recipes for pre cooked chicken and the curry (chicken achar) later this week
cheers
Update 2/1/2006:
I now add the following everytime to this base:
1 black cardamom at the initial frying stage (take it out before pureeing and pop it back in after, fish it out at the end)
And when simmering the onions I now add 1 slice of lemon (including peel), half a small green pepper, half a small carrot, 1 TSP fenugreek leaves, 1/2 TSP ground thyme, coriander stalks, small amount of creamed coconut (about 1 inch square or less). (thanks pete for all of that? ;D)
And when all that lot is in I add in the last of my previous base one spoon at a time. All of this then fries for a good 5-10 mins before pureeing.
