Yogurt is milk cultured with bacteria. The bacteria ferment the milk, giving it a sour tang.

Greek yogurt (strained yogurt) is strained through a filter to remove more of the whey, making a thicker yogurt with more protein.

Yogurt is versatile enough that I keep a container in my fridge at all times.


Look for yogurt in a resealable container (unless it's single-serving). Check the ingredient list and avoid yogurt with added sugar.


Store yogurt in the refrigerator in an airtight container (hopefully the container it came in). Store it in a cold part of the fridge, low and away from the door.

Yogurt can last a week or two past its expiration date, but throw it away immediately if:

During storage, some liquid whey will float to the top. This is normal. You can ignore it, or you can stir it back in to the rest of the yogurt.
