Sour Cream

Method

1. Mix the cream and lemon juice or white vinegar together in a jar then pour in the milk. Screw on the lid tightly and shake well.
2. Remove the lid and put a piece of paper towel over the jar and secure it with a rubber band.
3. Leave it on the bench overnight (up to 24 hours) for it to set.
4. After 24 hours it should be quite firm. Give it a stir and cover it with a jar lid. Keep it in the fridge for up to 2 weeks.
