Best Practices for Drying Red Chili Peppers
Choose the right method based on your resources and climate:
1. Air Drying (Traditional Method)
- Remove stems and wash peppers thoroughly
- String peppers together using a needle and thread
- Hang in a warm, dry, well-ventilated area away from direct sunlight
- Turn occasionally for even drying (1-2 weeks total)

2. Food Dehydrator (Fastest Method)
- Slice peppers in half lengthwise
- Place on dehydrator trays with space between pieces
- Set temperature to 50°C (120°F)
- Dry for 6-12 hours until brittle
3. Oven Drying (Backup Method)
- Preheat oven to 70°C (160°F)
- Place peppers on baking sheet lined with parchment paper
- Leave oven door slightly ajar with a wooden spoon
- Check every hour until brittle (4-8 hours total)
4. Sun Drying (Warm Climate Method)
- Spread peppers on clean mesh screen
- Place in direct sunlight with clear plastic cover
- Bring indoors at night to prevent moisture
- Check daily until fully dried (3-7 days)
Pro Tips for All Methods:
- Use only ripe, unblemished peppers
- Wear gloves when handling hot peppers
- Test dryness by bending - they should snap cleanly
