red peppers 2,

scotch bonnet chillies 3,
halved, deseeded and chopped
To sterilise the jars, wash in very hot soapy water then rinse in clean hot water. Put on a baking tray in a 130C/fan 110C/gas 1/2 oven to dry completely. Put a couple of saucers in the freezer to test the jelly later.
To make the jelly, put the jam sugar and vinegar into a large pan and heat gently, stirring until the sugar dissolves. Put the peppers and chillies in a food processor and pulse until finely chopped. Tip into the vinegar mixture and bring to the boil.
Keep boiling for 15 minutes, stirring constantly, then take out a teaspoonful and spoon it onto one of the plates from the freezer. Leave for a minute then run your finger through – it should wrinkle a little and look softly set. If not, simmer it for another 5 minutes and try again.
Pour into the sterilised jars and seal. Once opened the jelly will keep for a month in the fridge.
