Substitution

Some people say that Greek yogurt has a tangier taste than sour cream, while others cannot tell the difference. It is really up to the individual to determine if Greek yogurt is a suitable substitute for sour cream (or vice versa) since taste widely varies.

If you are not a fan of Greek yogurt, adding a dollop to a baked potato probably is not going to make you suddenly love it. However, when baking with Greek yogurt you probably will not notice a difference when substituting out sour cream in recipes like muffins, cakes, or cookies. This is true as well for dips, which contain a lot of added seasoning.

Note that Greek yogurt can curdle when exposed to high heat since it is lower in fat. It is best to use full-fat Greek yogurt when making something like a sauce and gradually bringing it  to temperature to avoid curdling. Trust me, lumpy sauce isn’t going to impress the in-laws at Thanksgiving.
