Instructions
Prepare chilies
Wearing gloves, remove stems from chilies. Roughly chop for easier processing. Keep seeds for more heat.
Time: 10 min
Tip: Mix chili varieties for complex flavor.
Blend to paste
Process chilies with garlic until smooth paste forms. Add salt and sugar, blend to combine.
Time: 5 min

Pack jar
Transfer paste to fermentation jar. Press down to remove air. Leave 1-2 inches headspace for bubbling.
Time: 5 min
Tip: Paste will expand during active fermentation.
Ferment
Seal with airlock and ferment 5-14 days at room temperature. Stir every few days.
Time: 5-14 days
Tip: Longer fermentation develops more complex flavor.
Blend and bottle
When desired flavor is reached, blend smooth if needed and transfer to storage jars.
Time: 10 min
Fermentation Timeline
