Wilt- what flavourings have you tried? I love ground cumin, a little cinnamon, a little chilli, heaps of garlic.... mmmmm! I also love cardomom. Sometimes I like smoked paprika, sometimes sweet paprika. Not a fan of turmeric, (but it gives a lovely colour). You can also dry fry some mustard seeds and put them in- the sky is the limit!
I wash it in a sieve.
