Step 1

Pour yogurt into a lined mesh strainer or colander that is placed over a bowl or large measuring cup.

Step 2

Place yogurt in your refrigerator and allow it to drain for 24 hours.

Step 3

Reserve strained yogurt for other purposes. (*See the link in recipe notes.)

Step 4

The liquid that has drained into the bowl or measuring cup is whey. Decant it into a lidded jar and store it in the refrigerator. Your homemade whey will last for 6 months.
