Yotsuba Q&A

There is water on top of my yoghurt. Is it safe to eat?

The water you can see is called whey, and is the moisture content of yoghurt. Whey contains many milk constituents and is highly nutritious. You may mix the whey into your yoghurt, or reserve the whey for adding to cooking, such as soups or miso soups. (Yoghurt whey has a tangy flavor.)
