Flavor profile

Sour cream's character is the product of lactic acid fermentation: Lactococcus and Leuconostoc bacteria produce lactic acid, diacetyl (butterscotch-dairy flavor compound), acetoin, and acetaldehyde in the cream — creating the characteristic tangy, slightly buttery, thick texture. The fat content (18–20% for regular, 35–40% for 'restaurant' or 'heavy' sour cream) is the primary flavor carrier. Sour cream cannot be boiled without breaking (the proteins coagulate and separate from the fat) — it should be added off heat or at very gentle heat, or tempered (heated gently mixed with a spoonful of the hot liquid before adding to the pan). Classic applications: baked potatoes (sour cream + butter is the American standard), in stroganoff (added at the end off heat for the creamy sauce), in borscht (a dollop on the surface), in coffee cake and muffins (the acid activates baking soda and creates tender crumb), in cheesecake (mixed into filling for tang and richness). Mexican crema (lower fat, pourable) functions similarly but with milder acidity.
