Cauliflower & Tomato Curry

This curry is from Gujarat state, which has a predominantly vegetarian population. The tomato sauce, with flecks of coconut and spices, gets its zing from tamarind, a signature flavour in their cuisine. Midweek I do use ready-made curry pastes and spice mixtures such as garam masala, but this is one dish that especially benefits from freshly toasted and ground spices.
