The traditional method for making any fresh masala is to start with whole spices. The spices should be toasted either in a heavy pan (such as cast iron) or in a low heat over (250 degrees) just until the aromas start to release. Over heating the spice will make it bitter and unpalatable.
You can use a combination of ground spices but of course you will not have the same intense flavor.
Makes about 1/4 cup of spice.
Preheat oven to 275F degrees. Combine spices on pizza pan or cookies sheet and bake for about 20-25 minutes, stirring occasionally.
In a blender container place roasted spices; cover and blend to a fine powder. Store in an airtight container in a cool dry place.
