Other than gardening I also enjoy cooking manly foods such as chili and BBQ rubs. One seasoning I have heard being used for both recently was jalapeno pepper powder. Not seeing any in local stores and having an abundance of jalapeno peppers in my garden I decided to attempt to make my own.
1. First picked some nice green jalapeno peppers from my garden, I chose to use young green ones but you could also use more ripe red ones for a different and less spicy flavor.
2. Next I cut the ends off the pepper, split them in half, and removed any seeds. After a little trial and error I noticed that if I cut perpendicular to the line in the middle of the pepper (see below) it was much easier to remove the seeds
3. I then placed the halved peppers in a plastic tray and put them in my dehydrator at 90F for 24 hours until they were brittle (when you break them in half they snap with minimal bending) with no soft or moist areas.
Tip: For difference flavor you can dehydrate at a higher temperature to roast/cook them a little but you will lose some of their heat.
4. Place your dried peppers into a blender or spice grinder and pulse until they create a fine powder.
Be sure to let the powder settle some and be careful to not inhale the powder, though much less heat then some of its pepper cousins (see chart below) getting a nose full of jalapeno pepper powder is not a pleasant experience (I did try this not too painful, though should have a nice little coughing fit).
As I mentioned above you can use this in meat rubs and chili but also can be used anywhere you may use other pepper powders. Some ideas I am thinking about is complement to Mexican foods, omelets, popcorn, and potatoes.
