Sweet and sour cherry marmalade

IngredientQuantityMeasurement
butter 1 Tablespoon
onion, thinly sliced 1

Step
Melt the butter in a heavy saucepan.
Add the onion, stir well, cover and simmer for about 25 minutes. It's important not to let it burn - it should soften down and colour gently.
Add the stoned and halved cherries, sugar and vinegar and simmer for about 15 minutes, until liquid has evaporated and you have a runny jam-like consistency.
Cool and store in an airtight container in the fridge until ready to use.
