Whilst, like many CR0 members, I am no great fan of Patak's products, I believe that it would be a foolish would-be BIR chef to assert that they have no place in BIR cuisine at all. Keeping an open mind, I purchased a pack of Patak;s South Indian Madras, composed of 3 sachets fastened together with an eyelet rivet. Separating them was not easy, but the cooking process was simplicity itself : gently bhoon the dry spices (mustard seeds, curry leaves, peppercorns and dried red chillies) in a little oil or ghee, add the sachet of spice paste together with 50ml of water, continue gently frying until almost all of the water has been driven off, add the pieces of chicken (or whatever), continue gently frying until they are sealed, then add the base and continue frying until ready. The results were, to be honest, no worse than many of us will have accomplished while trying to achieve BIR perfection, and quite possibly better than some more mediocre attempts. To my taste there was a little too much tomato in the base, and the end result was thicker than I would have wished, but overall this product does produce an acceptable end-product without requiring a major investment of time.
