Fermented hot sauce
- Published: 2 May 24

Far more complex in flavour than its vinegar-based cousins, James Read’s fermented hot sauce is one of the easiest ways to venture down the rabbit hole of home fermentation. All you need to get started is a clean jar, chillies, salt and some patience – before you know it you’ll be filling your shelves with gently fizzing jars of fiery goodness. See Know-how below for ideas on how to jazz up this base recipe, too.
Once you’ve mastered this recipe, have a bash at making kimchi.

Makes about 300ml, depending on how much you dilute it -
Hands-on time 10 min, plus at least 3 weeks fermenting
Before you start
Please wear gloves. When working with lots of chillies, it’s almost impossible to avoid getting capsaicin particles in unwanted places. If you’re without gloves, rub your hands with oil before soaping them (oil-soluble capsaicin dissolves more easily this way, then you can wash it all off).

TROUBLESHOOTING
If your hot sauce is…• Not fermenting
Chillies can be slow to get going, especially in a high-salt environment. If they take more than a couple of weeks, you may have to start again – although if there’s no sign of mould, you may as well leave your problem-batch running. Make sure the amount of salt is correct and try fermenting somewhere warmer.• Forming a white film while fermenting
This is probably kahm yeast, which can be a problem with longer ferments, especially if there’s a lot of sugar (for instance if you’ve added peach or
mango; see Know-how). It’s unlikely to be harmful, but can affect flavour slightly. Remove the film and continue fermenting. In hot weather, you may need to increase the brine to 5% (12.5g salt to 250ml water) to counteract this.• Forming a white film once bottled
This is rarer, but it’s still likely to be kahm yeast. Add some vinegar (1 tbsp per 150ml should do).• Too spicy
There’s not a lot you can do, except make it again with milder chillies. Mixing it with mayonnaise will subdue the heat. Or give it away – I’m always happy to receive a bottle of hot sauce.A few of James’ favourite blends
“The range of chillies, fruit and spices you can use while following the same basic steps of making hot sauce means you absolutely ought to experiment with different ingredients. I’ve adjusted the salt in each of these versions to account for extra ingredients.”• Bird’s eye and peach
Follow the base recipe, substituting the chillies with 150g bird’s eye chillies (roughly chopped) and 1 peach, peeled and roughly chopped. Add the peach to the jar, wedging in the pieces to stop them floating, followed by the chillies and brine, upping the salt to 12g.• Red habanero, pepper and onion
Follow the base recipe, swapping the chillies for 60g (4-6) red habaneros, ½ red pepper, deseeded, and ½ onion, all roughly chopped. Add the chillies,
pepper, onion and brine (with 11g salt) to the jar.• Mango, orange scotch bonnet and ginger
Follow the base recipe, swapping the chillies for 60g (4-6) orange scotch
bonnets, the flesh of ½ mango, a 1cm piece of peeled ginger and ½ onion, all roughly chopped. Add the ginger to the jar, then the mango, onion, chillies and brine, with 11g salt.• Scotch bonnet, mustard and turmeric (Bajan)
Follow the base recipe, swapping the chillies for 60g (4-6) orange scotch
bonnets, 50g fresh peeled turmeric and ½ onion, all roughly chopped. Add 1 tsp yellow mustard seeds to the jar, then the turmeric, onion, chillies and brine, with 11g salt. The turmeric amplifies the scotch bonnet flavour, making it even fruitier.• Pineapple and garlic
Follow the base recipe, substituting the chillies with 300g ripe pineapple,
20g garlic and 75g red habaneros, deseeded, all roughly chopped. Add the brine, increasing the salt to 15g. Use a 500ml jar.
