Liquid whey is most easily and economically obtained from raw milk that has naturally soured, or clabbered, on the kitchen counter. Clabbered milk is a very useful item for the traditionally minded cook and has the consistency and taste of drinkable style yogurt. In this video, I show you how this process works.
Unfortunately, not everyone has access to raw milk which may seem to preclude the use of unprocessed, liquid whey for fermentation purposes as it is not commercially available.
The good news is that whey can easily be extracted from plain yogurt from the store or that you make yourself with pasteurized milk.
In the video below, I show you the very easy process for obtaining whey in its liquid, whole food form from a quart of plain yogurt. I also discuss what to do with the leftover yogurt cheese once the whey has been extracted (hint: it makes a delicious stuffing for large pasta shells or lasagna).
Of course, you are going to want to source the best quality plain yogurt your budget can afford, ideally grassfed organic yogurt. But, in a pinch, even lowfat yogurt from commercial brands like Dannon from the supermarket can be used as a source for all your whey needs.
Liquid whey will last in a glass mason jar in the refrigerator for about six months although the flavor will grow stronger and more pungent over time.
Powdered Whey No Substitute for the Real Thing
Please note that powdered whey is never an adequate substitute for whole, unprocessed, liquid whey that you naturally separate from a fermented dairy product like clabbered milk or yogurt. Drying and powderizing whey even at low temperatures denatures the delicate proteins and virtually eliminates its beneficial probiotic properties. This article discusses more on the dangers of protein powder.
Uses for Liquid Whey
Liquid whey is an important ingredient in homemade baby formula in addition to it’s indispensable role as an inoculant for fermented foods and drinks. Unprocessed liquid whey is also wonderful to mix with filtered water and a little orange juice for a healthy, additive free, sports drink naturally loaded with electrolytes.
