Crushed red pepper flakes are basically just dried peppers that are not ground to powdered form. Because it has not been ground further, it will leave you a mix of seeds and pepper flakes. This condiment is often used to garnish pizza, soups, and stews to add a layer of spicy flavor. That said, it might not be a good backup for some recipes because of its coarse texture. The good thing is you can always use your handy spice grinder to ground it into powdered form.

If you're worried about the difference in texture, you can turn your crushed red pepper flakes into powder. Simply place a good amount in your coffee or spice grinder and pulse.

Transfer to a clean jar. In our experience, the sauce stores well at the coldest part of the refrigerator (e.g., in the way back) for a good 2-3 months. And, of course, always dip into it with a clean spoon/chopsticks to preserve it. If there’s any foul smell or the sound of gas escaping when you crack it open, discard it. But we’re betting it doesn’t last past the 2-week mark!
