Picking Your Peppers

  1. Determine which type of pepper will be right for your crushed red pepper flakes. With a whole family of peppers you can pick, base your decision on how hot of a pepper you can handle. Pepper hotness is measured by Scoville units–the higher the Scoville unit, the hotter the pepper. For example, a sweet bell pepper has zero Scoville units whereas the mighty Habanero pepper ranges from 100,000 to 350,000. The hottest pepper on the scale is the Trinidad Scorpion Butch at 1,463,700.[1]
  • Assess your overall needs. If you are creating the crushed pepper for home use and you like them hot, go for the hottest pepper you can find. However, if you are giving the flakes to friends, you may want to go with something a little tamer.
  • Test the pepper before you make your crushed flake batch. What may be considered to be hot to some may not be to others. Or you may not like the taste of certain peppers.

Creating Pepper Flakes

  2. Using a knife, carefully cut the pepper stems off. Then, slice peppers by simply splitting the peppers in half. Don’t remove the seeds.
  3. Line non-greased cookie sheets with peppers. Line peppers side by side and avoid clumping peppers together (otherwise they won’t dry properly).
  4. Bake in oven for approximately six hours. To be sure you give them enough time to dry, set a timer. Once six hours have passed by, turn off the oven and allow the dried peppers to remain in the oven overnight so they will continue to dry and dehydrate.
  5. The next day, place the dried peppers in a food processor or crush them by hand. Only crush peppers by hand if you are wearing gloves and are crushing the peppers while they are inside a plastic bag. Otherwise, stick with the food processor.
  6. Once the dried peppers have been thoroughly crushed, carefully pour them in an airtight container. Serve the crushed peppers.[2]
