What are the possible substitutions for Cumin in Indian cuisine?
You know, I don't think you need to overthink this too much. If you look at a typical Indian curry recipe, it might have 10 spices in it. Just leave out the cumin, and maybe bump up the other spices a little to compensate. It won't be exactly the same, but it will still be delicious. You are correct that you'll have to be careful to avoid pre-packaged spice mixtures unless the ingredients are spelled out. Here is my Chana Mushroom Masala, from which you can safely omit the cumin: http://www.herbivoracious.com/2009/09/quick-chana-mushroom-masala-chickpea-curry-recipe.html
