Fermented Herb Paste recipe

This deliciously pungent paste will keep for up to 1 year in the fridge. 

Try putting your Fermented Herb Paste to work in this ultra-creamy avocado dip: In a food processor, pulse 1/4 cup raw unsalted almonds until finely chopped. Add  1/2Ž cup Fermented Herb Paste, 1/2Ž avocado, peeled and pitted, 1 clove garlic, roughly chopped, 1/4 tsp  lemon zest and 1 tbsp fresh lemon juice. Pulse until combined and creamy.

  • Prep Time
  • 1 cupServings


  • 2 cups packed fresh basil leaves  and tender stems
  • 2 cups packed fresh parsley leaves and tender stems
  • 1 large clove garlic, crushed
  • 1/4 tsp sea salt
  • 1 small green or purple cabbage leaf


  • 1 8-oz wide-mouth glass jar with lid, sterilized


1. To a food processor, add basil and parsley; pulse until finely chopped. (TIP: If you don’t have a  food processor, you can finely mince herbs.) Add garlic and salt; pulse to combine. Let mixture sit until liquids release, about 5 minutes. 

2. Transfer herb mixture to an 8-oz wide-mouth glass jar. Using a spoon or your hand, press mixture down firmly to release liquid and remove any air pockets, pressing until ingredients are completely submerged and leaving 1 inch head-space between herb mixture and rim of jar. 

3. Arrange cabbage leaf directly over top of herb mixture to keep herbs submerged in liquid; seal loosely with lid. 

4. Let ferment in a cool place away from direct sunlight, pressing down on cabbage every 24 hours  or as needed to keep herb mixture submerged in liquid, for 5 to 10 days. (TIP: Begin tasting on day 5 and continue to ferment until mixture reaches desired acidity.) 

5. Discard cabbage leaf and top pesto with waxed paper. Seal tightly with lid and refrigerate for up to 12 months.
