Sour cream is fermented cream made by adding lactic acid bacteria to the whipping cream and left to multiply over a few hours similar to making yogurt. The bacteria thickens the cream naturally but, often store-bought sour cream will have artificial thickeners added to it. It is a gluten-free product and perfect for so many things from cake batters, to onions dips and sandwich spreads.

Best known as a topping on Mexican-American favorites like burritos and nachos, sour cream is a divisive condiment that diners either love or love to hate. With a high fat content and creamy texture, sour cream is an easy and indulgent way to add richness and acidity to just about any savory or sweet dish.
