How do I make a good sour cream?
assistant
To make a good sour cream, you will need to start with heavy cream. Then add 1/2 teaspoon of lemon juice or white vinegar per cup of cream and let it sit for about 10 minutes before stirring in 1/4 teaspoon of sugar per cup of cream. Finally, stir in a pinch of salt and any desired herbs or spices.
