How should chili seasoning be stored?Store in an airtight container or a spice jar. The chili seasoning will stay fresh for as long as the spices that you used would stay fresh. So, if you don't plan on using all of the chili seasoning right away, be sure to use fresh spices that have a further out expiration date. Many spices are good for a couple of years if stored in a pantry in an airtight container. Older spices start to dull in color or start to clump together.Is chili seasoning spicy?It depends on how much cayenne pepper and red pepper flakes you put in the seasoning mix. My recipe for chili seasoning is not spicy. I like to add more spice when I make chili by adding jalapenos, spicy beans, and tomatoes with chilis added in. If you like your chili spicy, feel free to add more cayenne pepper or red pepper flakes to the recipe.
