Absolutely! There are plenty of ways to use your liquid whey ;) If you are using leftover whey from making mozza and you have salted the liquid remember to adjust your recipes that also use salt.In baking, substitute it for water when making pancakes, muffins, bread and pizza dough. It can be added to water when boiling or cooking potatoes, rice, pasta, grains and beans. It can be used in soup stocks or in a smoothie to increase your protein content. You can give it to your cat and tomato plants in small amounts.It freezes and thaws very well and will last up to 2 weeks in the fridge.
