I also have a variety of spices & I think what I use really depends on my mood. I've got Italian spices for SW pizza, chilli, garlic, cumin, chinese, I also have an Asian shop nearby & often go in there & just pick up spices such as Masala, Dahl, why not go to the shop, take a look at all the spices & think how you really would like your food to taste, you can't buy them all in one go, it's something which needs building up over time.
