Ingredients
Quantities are shown as originally provided.
- 3 cups Peppers (- Roughly chopped (350 grams))
- 1 Small shallot (- Peeled and roughly cut)
- 4-6 Garlic cloves
- 1 ½ tsp Kosher salt (- 10 grams (see note about salt amount))
- 1 tbsp Rice vinegar (- Use more or less to taste)
- 2 tsp Lime juice (- Use more or less to taste)
Instructions
- 1
Weigh the pepper mix. To a bowl, add your chopped peppers, garlic and shallot. Weigh the mix.
- 2
Salt the pepper mix. To determine how much salt you need, multiply the weight of the peppers by 0.03 (or 3%). Add the salt to the peppers. Note: if you do not plan to ferment the pepper mix, you can season with salt lightly and adjust the seasoning later.
- 3
Rest. Stir the pepper mix so that the salt can be distributed and set aside for 15 minutes so the salt can dissolve into the peppers.
- 4
Transfer to a food processor. Transfer the pepper mix to a food processor, along with any liquid in the bowl.
- 5
Blend. Blend the pepper mixture into a coarse paste. Don’t over process.
- 6
Ferment (Optional). Transfer the pepper mash to a mason jar, add a fermentation weight (optional) and fermentation lid (optional). Ferment for at least 3 days at room temperature. If using a regular mason jar lid, burp it daily to release any built-up gasses. After 3 days, you can move on to the next step (or ferment longer if you prefer). Optionally you may strain your sambal to remove any excess liquid.
