What Is Chilli Jam?

Chilli jam is a sweet chilli preserve made by simmering chillies, peppers, sugar, and vinegar until thick and spoonable. Unlike sweet chilli sauce, it’s sticky and rich, with deeper flavour and a jam-like set.

Ingredients (Makes 3–4 jars)

• 8 red chillies (medium heat works best)
• 2 red peppers
• 5 cloves garlic
• 750 g jam sugar
• 250 ml red wine vinegar or cider vinegar
• 1 tsp salt

Optional flavour boosts (choose one or two):

• 1 tsp smoked paprika
• 1 tsp grated fresh ginger
• 1 tbsp soy sauce
• Juice of 1 lime

How Hot Is This Chilli Jam?

As written, it’s mild to medium.

• Milder: Remove chilli seeds or use fewer chillies
• Hotter: Add extra chillies or a hotter variety
• Sweeter: Add a little extra sugar at the end if needed

Step-by-Step Method

1. Prep the Ingredients

Roughly chop the chillies, peppers, and garlic.
(Leave seeds in for more heat; remove for milder jam.)

Blitz in a food processor until finely chopped but not puréed.

2. Start Cooking

Tip the mixture into a large, heavy-bottomed saucepan.
Add the jam sugar, vinegar, and salt. Stir well.

Bring to a gentle boil over medium heat, stirring until the sugar dissolves.

3. Simmer to Thicken

Lower the heat and simmer 45–60 minutes, stirring occasionally, until thick, glossy, and deep red.

You’ll know it’s ready when:

• It coats the back of a spoon
• A spoon dragged through leaves a clear line
• It thickens further as it cools

4. Jar the Jam

Carefully spoon the hot chilli jam into sterilised jars.
Seal immediately and allow to cool.

How Long Does Chilli Jam Last?

• Sealed jars: Up to 12 months
• Once opened: Refrigerate and use within 4–6 weeks

Always use a clean spoon to avoid spoilage.

Best Ways to Use Chilli Jam

• Cheese boards (cheddar, brie, goats’ cheese)
• Burgers, sausages, bacon sandwiches
• Glaze for chicken or pork
• Stirred into gravy or sauces
• Spread on toast or crackers
• Added to marinades

A little goes a long way.

Chilli Jam vs Sweet Chilli Sauce

Chilli jam: Thick, sticky, spoonable, deeper flavour
Sweet chilli sauce: Runny, sharper, more vinegary

They’re related — but not interchangeable.

Can You Make Chilli Jam Without Jam Sugar?

Yes, but jam sugar gives the best set.

• Use granulated sugar
• Add lemon juice for acidity
• Simmer longer to thicken

Texture may be slightly looser.

Common Mistakes to Avoid

• Boiling too hard (can burn sugar)
• Underestimating how much it thickens as it cools
• Using very hot chillies without tasting
• Overfilling jars

Low and slow wins.

Final Thoughts

This chilli jam recipe delivers the perfect balance of sweetness, warmth, and richness. It’s sticky, glossy, and endlessly useful — from cheese boards to weeknight dinners.

Once you’ve made it at home, shop-bought versions won’t compare.
