I made my latest batch a week past. This is my favourite base. It's minimalist, provides the volume and consistency, and lets your spices do the work. I made a Jalfrezi tonight using some green pepper, onion, 2 cloves finely chopped fresh garlic, 1 or tsp tomato paste, fresh chilies, 1 tsp BE spice mix, a pinch of methi and a small handful of freshly chopped coriander - standard cooking method. It's the best I've had in a while, and easily puts to shame any of my attempts with the Ashoka recipes.
