Can you freeze Yogurt?

Listed quality estimate: Yogurt keeps 1–2 monthsat continuously 0°F (−18°C) or below, if safe when frozen. Check the source status on the storage card; this is not a discard deadline.

Yogurt is safe to freeze, but its smooth texture breaks down once thawed, turning watery and grainy as the whey separates from the curd. Freeze it in a rigid tub with a little headroom, or spoon it into ice-cube trays, for 1–2 months. Thaw in the fridge and whisk well; use it in smoothies, baking, or cooking rather than eating by the spoon.
