I believe the word Balti actually means "bucket"....this famous style of curry is cooked in a balti pan, much like a wok. I think the reference to bucket means more that you can throw anything in! I fell in love with balti curries years ago living in Birmingham UK - a few blocks from balti central. What sushi bars are to Vancouver, balti houses are to Birmingham. I know this is a very anglo version of balti sauce, a very mild one at that, but it is quite healthy and light....and not lacking any flavour. It's also fairly quick to prepare compared to some recipes I've tried. You can boost up the heat factor as you wish. I included mainly ready ground spices, but of course you could use whole. If you use whole cardamom seeds or whole coriander I would suggest grinding the spices up after you roast them (otherwise you have a lot of woody bits to deal with). Use the sauce to make any kind of veggie curry and serve with naan or roti on the side. This makes 3 cups of sauce - enough for 4 servings. I like to save half the sauce for a different curry later on. (good for a fridge cleaner curry! :) It also improves overnight, as many sauces do. Hope you enjoy!
