Spice up your meals with Symbiota’s fermented hot sauce!


Raw, tangy, and alive with probiotics, this hot sauce is naturally fermented, and packed with gut-loving microbes. Perfect for adding heat and flavour to anything from eggs and toast to soups, stews, and stir-fries.

Ingredients (Makes ~100ml)

  • 250g fresh chilli peppers (mild, medium, or hot)
  • 250g of fresh veggies (a mix of carrot, onion, capsicum, cauliflower etc)
  • 3 cloves garlic, peeled
  • 1 tablespoon (flat) Himalayan salt
  • 2 cup filtered water

Instructions

  1. Prepare the chillies and veggies: Slice or roughly chop the chillies, veggies and garlic. For less heat, remove seeds from chillies.
  2. Combine in a jar: Place chillies, veggies, garlic, salt, and sugar (if using) in a clean jar.
  3. Add water: Pour in filtered water to just cover the ingredients.
  4. Ferment: place a weight on top or produce and an airlock on you jar and leave at room temperature (18–23°C) for 7-21 days, tasting daily until tangy and bubbly.
  5. Blend & Bottle: Transfer the fermented veggies to a blender while reserving the liquid behind. Slowly add the liquid as you blend until desired thickness. 
  6. Store: Pour into sterilized bottles. Keep refrigerated for up to 6 months.
