Yippee. Vaccuum sealing and fermenting chillis do go together, radically reducing the risk of taste tainting yeasts.
So, there is a West African restaurant in London called Ikoyi and they have this recipe for fermenting chillis:
Lacto-fermented scotch bonnet chillies (makes 400g)
500g scotch bonnet chillies, halved and deseeded
10g fine salt
Mix the chillies and salt in a large vacuum-seal bag and toss well to distribute the salt. Make sure the chillies are evenly spaced out in a single layer. Seal the bag on full and leave to ferment for seven days at 24-28°C (75-82°F). If the bag has expanded too far, “burp” out the air by making a small incision and then reseal.
Once the chillies have reached a sour, fragrant and meaty flavour profile, store them in an airtight container in the fridge and use within two months.
I have tried it out and got these:
They are tasty fermented scotch bonnet chillis that you can eat, sparingly, with your food. Their book also has a recipe for a hot sauce which will use these fermented scotch bonnets as an ingredient but you first have to ferment some blended chillis (I used longer, less hot chillis for this) for a couple of weeks. Watch this space. I am hoping for a delicious fermented sauce at the end of all of this.
