Question: what is the difference between table cream and sour cream?
Answer: Sour cream is the product of a lactic fermentation, which tales place for a short time. The byproducts of the fermentation give it its tangy acidic taste. Sour cream has about 18-20% butterfat. Crema is more akin to Crème fraiche which has a higher butterfat content at around 28% and only very slightly acid content.
