Here is your basic curry powder blend.
These are the staple ingredients that make up your basic curry powder. Again this can be purchsed all premixed from your local grocery store. I've found many different kinds of curry mixtures as asian markets that are very delicious!
Place all ingredients in a container with an airtight lid. Shake to combine. Store in a cool dry place for up to 6 months. When ready to use, grind and add to dishes according to taste. Also you can add many of other spices to the curry blend in order to give it a pairing flavor to the dish you're creating. Cinnamon, saffron, cloves, white pepper, fennel, and nutmeg are just a few addons that can be blended in.
