Homemade chili sauce will last 2-3 weeks in the refrigerator in an airtight container. You can also freeze it for up to 6 months.

Chili peppers offer a range of potential health benefits due to their nutritional content and the presence of capsaicin, the compound responsible for their heat. Some of the potential benefits of chili peppers include:

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!

It also lacks the extra ingredients that you'll find in most blended chili powder preparations. You can substitute one for the other in some recipes, but you might need to adjust your other ingredients to account for the change in flavor.
