Storage & Preservation
Fresh Thai Dragon peppers store best at room temperature for 3-5 days or in the refrigerator crisper drawer for 1-2 weeks. Their small size makes them prone to faster moisture loss, so store in a perforated plastic bag to maintain humidity while preventing condensation buildup.
For preservation, these peppers excel at drying due to their thin walls and small size. String them on thread or spread on dehydrator trays at 135°F for 6-8 hours until brittle. Properly dried Thai Dragons retain their heat and flavor for over a year when stored in airtight containers.
Freezing works well for cooking use — simply wash, dry, and freeze whole peppers in freezer bags. They'll lose their crisp texture but maintain full heat and flavor for sauces and stir-fries. For hot sauce making, ferment whole peppers in a 3% salt brine for 2-4 weeks before blending with vinegar for complex, developed flavors.
