If you're looking for a dairy substitute in your cooking and recipe. Then you might have asked yourself if sour Cream can be used as a substitute for light cream. The answer is yes, but there are some things that you should consider first. Besides, sour Cream does contain some fat content, but it is significantly lower than light or heavy creams. In terms of taste, it will work best in savory dishes—for example, Mexican foods or pizza toppings instead of desserts like custards and pastries. Additionally, note that sour Cream doesn't make a great substitute in recipes that require whipping. Where its water content will dilute whatever ingredient you're trying to whip. However, it works well enough when added as an ingredient early on before heating up.
