Scotch Bonnet Sauce Recipe – Simple Homemade Hot Sauce

This Scotch Bonnet sauce recipe is one of the originals here at The Chilli King — published back in 2010 and still one of our most made recipes. And for good reason: it’s incredibly simple, takes under 20 minutes from start to finish, and produces a sauce with genuine Caribbean heat and the distinctive fruity flavour that makes Scotch Bonnets so special.

Unlike many commercial hot sauces which are padded out with tomato, carrot or other fillers, this recipe is essentially just chillies, vinegar and a handful of store cupboard ingredients. The result is a pure, intensely flavoured sauce that’s all about the Scotch Bonnet. If you’ve grown your own this season and are looking for the best way to preserve and enjoy that flavour, this is it.

The recipe made enough for one bottle when we first published it. Most readers now make at least double or triple the batch — you’ll understand why once you’ve tasted it.

A Word on Scotch Bonnets

Scotch Bonnets (Capsicum chinense) are one of the most distinctive chillies in the world. Closely related to the Habanero — they’re essentially regional variants of the same species — they share that characteristic fruity, floral heat but with a slightly different flavour profile that’s synonymous with Caribbean cooking. The name comes from their shape, which resembles a traditional Scottish tam o’shanter hat.

Heat-wise they sit between 100,000 and 350,000 Scoville Heat Units — significantly hotter than a jalapeño (2,500-8,000 SHU) but below the superhot varieties. They’re not a casual heat — twenty Scotch Bonnets in a small bottle of sauce means a few drops go a long way. See our Chilli Heat Guide for a full comparison of heat levels.

For the best flavour use fully ripe red or orange Scotch Bonnets — unripe green bonnets will produce a sauce with a grassier, sharper flavour. See our guide to knowing when chillies are ripe if you’re using homegrown fruit.

Safety First — Please Read Before You Start

Scotch Bonnets contain very high concentrations of capsaicin which penetrates skin rapidly and can cause prolonged burning. This isn’t a light warning — several readers have made this recipe and reported burning hands for hours afterwards.

Always wear nitrile gloves when chopping and handling Scotch Bonnets. Latex gloves are less effective as capsaicin can permeate latex over time. Nitrile gloves are inexpensive and worth keeping in your kitchen if you regularly cook with hot chillies.

Never touch your face — particularly your eyes — while handling Scotch Bonnets even if you’re wearing gloves.

Open your windows when cooking. The steam produced when Scotch Bonnets simmer in vinegar is intense — essentially aerosolised capsaicin — and can irritate eyes and throat even from a distance. JD in our comments described the fumes as “crazy” — take this seriously and ventilate the kitchen thoroughly.

If you get capsaicin on your skin: don’t use water — it spreads the oil. Use milk or a dairy product to remove it, or wash thoroughly with washing up liquid which helps break down the oil.

Scotch Bonnet Sauce Ingredients

20 scotch bonnets (100g when chopped)
100ml of red wine vinegar
3/4 teaspoon of salt
2 teaspoons of brown sugar
100ml water

Method

Roughly chop the scotch bonnets, removing the stalks and any excess seed membrane (i leave most of the seeds in). Add the scotch bonnets to a food processor and blitz for a few seconds until they are finely chopped. Next add the chopped scotch bonnets to a small pan along with the vinegar and salt and bring to the boil. Turn down the heat and simmer for 5-10 minutes until the peppers have softened.

The mixture should reduce down a bit. Keep an eye on it so it doesn’t burn or dry out too much. When it starts to look like it might dry out, add the water and sugar then stir and simmer for a further 4-5 minutes. Remove from the heat and allow to cool.

Meanwhile take your glass bottle/s and sterilize by either boiling in water or heating in the oven for 5 minutes.

Once cooled and your bottles are almost ready add the sauce back into your food processor and blitz until smooth. Add the sauce to your sterilized jars, seal and allow to cool.

The sauce should keep for several months unopened and at least 12 weeks once opened and kept in the fridge.

Note: The above recipe made one bottle of sauce. However as you can see from the photo i was forced to give half of it away and the remaining half has not lasted long despite being blistering hot!

Hot Sauce Tips and Technique

The vinegar simmer is important. Cooking the chillies in vinegar before adding the water does two things – it softens the chilli flesh so the sauce blitzes completely smooth, and the acid in the vinegar acts as a natural preservative that gives the finished sauce its long shelf life. Don’t rush this stage. Five to ten minutes at a gentle simmer is what you’re aiming for – you will see the chillies lose their brightness and soften noticeably.

Add the water and sugar at the right moment. Once the chillies have softened and the vinegar has reduced slightly, add the water and sugar. The sugar balances the sharp vinegar edge and brings out the natural fruitiness of the Scotch Bonnets. Stir well and watch the pan as at this stage it can catch quickly if the heat is too high so keep stirring.

Cool completely before blitzing. This is the step most people skip in their impatience and then regret. Blitzing a hot sauce in a food processor can build up steam pressure and you risk the lid coming off. Allow the mixture to cool to room temperature first (it takes about 20 minutes) then blitz until completely smooth. The sauce will lighten slightly in colour as air is incorporated during blending.

Sterilise properly. Sterilising your bottles/jars is very important when it comes to ensuring the shelf life of your sauce is maximised. Ten minutes in boiling water or a hot oven is all it takes. A properly sterilised bottle is the difference between a sauce that keeps for months and one that goes off within weeks. Don’t skip it.

What to Serve With Scotch Bonnet Sauce

The fruity heat of Scotch Bonnets makes this sauce extraordinarily versatile — it works with almost anything that benefits from heat:

• Chicken wings — Simon’s suggestion in the comments and our personal favourite. The sauce glazed over wings before grilling is exceptional
• Jerk chicken or pork — the Caribbean connection makes this a natural fit
• Rice and peas — a few drops stirred through transforms a simple dish
• Fried eggs — drizzled over fried eggs on toast is a revelation for those who can handle the heat
• Cheese on toast — sounds unusual but the sweet-fruity heat works brilliantly against strong cheddar
• BBQ — used as a finishing sauce or marinade base
• Curries — a few drops added to a mild curry dial up the heat beautifully without changing the flavour profile
