What is whey?

When I started making cheese I was shocked at the amount of fluid left in the pot after the curd had formed. I quickly learned that the yellowish straw-colored fluid is called whey. So what to do with all that whey? It seemed such a waste to throw it away! Then I learned about the health properties in whey and I stood amazed! It contains calcium, magnesium, potassium, b-vitamins, thiamine, riboflavin, phosphorus, selenium and zinc!

First of all you need to know that there are two types of whey:

A) Sweet whey: The whey you get from making cheese with rennet

B) Acid whey: The whey you get when an acid like vinegar or lemon juice is added to make for instance cream cheese

Here is 20 things to do with all that healthy whey: 

  1. Feed it to the dogs
  2. Feed it to the chickens
  3. Freeze it in ice cube trays to use in smoothies for extra protein
  4. Dilute whey with water and water your plants with it (make sure it is whey with rennet in and not lemon juice)
  5. Make mayonnaise
  6. Use it as a substitute for buttermilk when baking biscuits or a substitute for any recipe that calls for water or milk, especially when baking bread or making pizza dough.
  7. Use it to soak grains (like beans) to make them more digestible
  8. Soak nuts in it, your digestive system will thank you for it!
  9. You can use it as a toner on your face or even add some to your bathwater for an over-all body treatment. Some people even say you can use it as a hair rinse instead of a vinegar rinse.
  10. If you are growing peas, cucumbers or squash your plant will benefit from spraying sweet whey (the ones made from rennet) on the leaves. It kills mold that might be growing there.
  11. Use it on roses, blueberries or tomatoes in the garden to make the soil more acidic.
  12. Or alternatively add it to your compost pile.
  13. Add whey to soups or stews
  14. Use it as a meat-tenderizer in marinade instead of vinegar.
  15. Use it to cook rice, pasta, potatoes or oats. It will add extra flavor to your food
  16. Make lemonade
  17. Make ricotta. The word ricotta means “twice cooked” because it was traditionally made from whey.
  18. Use whey as a substitute for lemon juice in recipes.
  19. Use it as brine for homemade feta cheese
  20. Ferment different foods with it.
