How to Measure Sour Cream Accurately
Spoon and level in a dry cup — the same rule as Greek yogurt, and for the same reason: too thick to pour honestly, too sticky to trust a liquid measure. At 245 g per cup it is marginally heavier than water and essentially interchangeable by weight with Greek yogurt.
Storing Sour Cream & Common Substitutes
Storage
Sealed and refrigerated, 1–2 weeks after opening. Sour cream grows mold at the edges long before it smells bad — check the rim under the lid. A little weeping is normal; stir it in rather than pouring it off to keep cakes and dressings at the right richness.
Substitutions
Greek yogurt 1:1 (tangier, a bit leaner). Crème fraîche 1:1 where the heat is high — it resists curdling in sauces that would break sour cream. In baking, buttermilk replaces sour cream cup-for-cup with baking soda adjusted up by a quarter teaspoon.
