How to Make Your Own Chile Pepper Flakes from Garden Fresh Peppers

If you like your food with a little spice, you might be in the habit of sprinkling dried chile pepper flakes onto your meals. Or in your favorite recipes. Why not try making your favorite spice at home, from locally grown garden fresh peppers?

We like our food with a bit of spiciness. Not crazy hot, but just enough heat to make our mouths happy. Growing hot peppers in our garden just makes sense. I like to grow jalapeño peppers, but since we’ve moved to the island, we also grow Hawaiian chile peppers. The plants are prolific and they’re perennial, so we almost always have fresh hot peppers at our disposal.

Even so, it’s handy to have a shaker jar of dried chile pepper flakes on hand for cooking. We use them in our homemade Italian sausage recipe, stir them into soups, and add them to my homemade taco seasoning. I also like to package these chile pepper flakes into small jars to give as gifts from the garden.

What’s the difference between chile peppers and chili peppers?

Nothing and everything. Chile peppers are hot peppers. There are countless varieties of chile peppers, all with a different heat intensity, color, and shape. When people type out “chili peppers” they’re referring to this group of spicy capsicum, but have mistakenly used an i where an e should go. The term chili usually refers to a chili recipe made with beef and beans.

Making dried chile pepper flakes

When working with chile peppers, be mindful that they burn. Don’t accidentally rub your eye after you’ve been working with them. You may want to protect yourself from that possibility by wearing rubber gloves when you’re making these dried chile pepper flakes.

Depending on the size of the peppers you’re working with, you can either dry them whole (as I did, with the Hawaiian chile peppers) or slice them.

In order to make chile peppers shelf stable, you’ll need to remove all of the moisture from fresh peppers. Slicing them into smaller portions can help this process move along more quickly. Once sliced, it will take six to eight hours in a dehydrator until they’re ready to crush.

You can make as much or as little of these dried chile pepper flakes as you like; you’ll end up with about half as much dried pepper as the amount you start with. One cup of fresh hot peppers will net about a half cup of dried chile pepper flakes.

(The cool long-handled wooden measuring spoon you see here was a gift from Andrea, the founder of Utensi, whom I met at a conference awhile back. Isn’t it great??)

    I made some pepper flakes for a friend. She sent me some not-too-hot pepper seeds to plant. Got a bunch of peppers. Within two days of the hot South Carolina summer the peppers were dry and ready to be turned into flakes. She enjoyed the freshness of the flakes.
