A pack of fresh cranberries – I used Ocean Spray.
Juice and zest of a good sized orange
A generous glass of port – ruby or tawny, either will do.
Sugar to taste.
Place all the ingredients in a saucepan and bring to the boil.
Simmer until reduced by about a third in volume.
Cool and place in clean jars.
Store in the fridge.
The sugar content is a personal thing – I quite like my conserve to be quite sharp, which may not suit all tastes. Add in tablespoons and taste regularly – a cook’s perk!
