One of the most useful things in my kitchen is my Masala Dabba, an Indian Spice Box.
Most of the yogic recipes I make include cumin seeds, black mustard seeds, turmeric, curry powder, asafoetida, coriander powder and cumin powder. Sometimes a few, sometimes all. Digging them out of the cupboard doesn't help if you're trying to keep your cooking time hassle free.
Easy to find in Southall or Leicester, you can always get one online here
