I told you last week that it’s my amazing husband’s birthday soon.

I don’t know if your significant other is the same, but he is not really easy to buy for.

He loves books, but usually they are very expensive theology books that he’d rather buy himself.

He needs new clothes but likes to buy those himself as he likes blue, black, and white, and that’s his limit.

I asked if he would like any new tools, but he said no because that means I’d have more jobs for him to do!!! The cheek!! (he’s right, but still…) 🙂

So Fermented Hot Sauce it is! He loves this stuff, so a bottle to himself is the perfect present for my heat loving honey.

Why Fermented Hot Sauce, not regular?

Fermentation is a form of preservation that has been around for years. It is basically a controlled method of harnessing the helpful bacteria present on the fruit of vegetable, and encouraging it to grow, using salt and water, to then keep the harmful bacteria away. The fermentation process also does a few things to the food:

  • It increases the vitamins and minerals in the food
  • It makes the vitamins and minerals more easily available for your body to use
  • It creates gut friendly bacteria to help your body’s immune system.
  • It increases the flavour
  • It can help reduce inflammation in the body

These are all amazing reasons to add more fermented foods and drink to our diet, and if you want to know more, check out our Fermenting page

This hot sauce is a delicious way to begin.

How do you make fermented hot sauce?

The sauce part of this hot sauce is really simple.

All you’ll need is:

The Fermented Peppers recipe

A few spoons of the liquor that the peppers were fermenting in

A blender



Vinegar, white or Apple Cider Vinegar


Oil – I used olive oil for this


It really is as easy as putting all the ingredients in the blender and turning it on!

Tasty Additions:

  • Peaches
  • Caramelised onions
  • Ginger and lemon

How do you store fermented hot sauce?

Once you’ve blended the sauce, you can use a funnel to pour it into a glass jar/ bottle and store in the fridge. This slows down the fermenting process and holds the flavour that you’ve developed.

It will keep in the fridge for around 12 months, but as with all ferments, check for signs of mould or a pungent odour, and if so, throw it out.

Can I cook fermented hot sauce?

Not really, it can be used on hot things, like as a topping to chicken, meat, or say, pizza. However, cooking the sauce will kill all the good bacteria we spent so long trying to grow! This will neutralise all the health benefits of the sauce.

Will it keep to give as a gift?

Absolutely! A pretty bottle, a tag and you have a homemade gift! Write on the tag when it was made and instructions to keep refrigerated, and they have a gift that will last!

So what would you add to the sauce? Are you and Extra spicy, or a mild sauce lover? Let me know in the comments below. Until next time friends x
