Recipe Author: Simmie Sinow
16 ozs plain nonfat yogurt
1 tsp lemon juice
Water as needed
Combine the yogurt and lemon juice and whisk well. Taste test the mixture to make sure it has enough of the tartness/sourness of sour cream that you enjoy -- if not, add a little bit more of the lemon juice until it reaches the right flavor.
Modify the thickness a little bit at a time by adding 1/2 tsp of hot water and whisking well until it gets to the consistency that sour cream is.
This can also be done using Dill Weed instead of the lemon juice. The amount of dill weed to be used varies depending on the brand of dill weed that you use.
