How can I effectively store peppers to ensure their freshness and flavor for a longer period of time?

To effectively store peppers and maintain their freshness and flavor for a longer period of time, you should place them in a perforated plastic bag in the refrigerator's crisper drawer. Avoid washing them before storing, as moisture can cause them to spoil faster. Peppers can also be frozen after being washed, sliced, and seeded for longer-term storage.
