To remove water from yogurt, you essentially strain it using a method that allows the watery whey to separate from the solid yogurt components.
Here's a breakdown of the process:
-
Prepare the Straining Setup: Line a colander with cheesecloth (several layers), a coffee filter, or a yogurt strainer. Place the colander over a bowl to catch the draining liquid.
-
Transfer the Yogurt: Gently spoon or pour the yogurt into the prepared filter.
-
Protect the Yogurt (Optional): Cover the surface of the yogurt with plastic wrap, pressing it lightly against the surface to prevent a skin from forming. This step is optional but recommended for best results.
-
Refrigerate and Strain: Place the entire setup (colander, bowl, and yogurt) in the refrigerator. Allow the yogurt to strain for several hours, or even overnight, depending on the desired consistency. The longer it strains, the thicker it will become.
-
Monitor the Whey: You'll see the whey (the watery liquid) collecting in the bowl beneath the colander.
-
Adjust Straining Time: Check the yogurt periodically. If it reaches your desired thickness before the allotted time, stop the straining process.
-
Collect the Result: Once the yogurt has reached the desired consistency, transfer it to a clean container and store it in the refrigerator. Discard the collected whey (or use it for other purposes, such as in baking).
Why Remove Water from Yogurt?
Removing water from yogurt creates a thicker, creamier product. This process is often used to make Greek yogurt, which has a characteristically dense texture. Strained yogurt also has a tangier flavor due to the concentration of acids as the whey is removed.
Alternatives to Cheesecloth:
While cheesecloth is the traditional method, you can also use:
- Coffee filters: These work well for smaller batches.
- Yogurt strainers: These are specifically designed for straining yogurt and can be found online or in kitchen supply stores. They are often easier to use than cheesecloth.
- Clean muslin cloth: Similar to cheesecloth, but often more durable.
