Read on for her tip! I'll announce the Reuse Roundup winner this Monday :)
I love your idea of tips to limit waste. We so often waste things that may seem insignificant to us, but with a look work can become something extremely valuable.
I pretty regularly make homemade Mozzarella cheese.
After the cheese is finished, you are left with a huge pot full of whey. Most people dump it down the drain; the thought of that pains me. Whey is incredibly versatile and can be used in more than just the kitchen which is why I love it so much. Here are a few ways to use it…
1. Homemade Ricotta cheese - Ricotta is one of the simplest cheeses to make, especially when using whey. Simply heat the whey up to 200 degrees, take it off the heat and allow it to cool to 140 degrees, strain it, and you have Ricotta (I’d suggest looking up more detailed instructions if making it, but that’s the gist of it).
2. Add protein to a smoothie/milkshake - I have a smoothie pretty much every morning, and adding whey gives it a boost of protein without having to buy protein powder.
3. Lacto-fermented Pickles (or other vegetables) - if you’re a fan of lacto-fermented vegetables but usually make them with salt, try making them with whey instead. The fermentation time is usually faster, and you don’t run the risk of getting vegetables that are super salty.
4. Water your garden - your vegetable plants will greatly benefit from being watered with whey (just make sure to dilute the whey with water)
5. Substitute for liquids in baking - I have used whey as a substitute for milk and/or water in countless recipes. Breads, muffins, pancakes, you name it. If it has a liquid in it, whey can be substituted at a 1:1 ratio. It tends to give your baked goods a taste more similar to sourdough.
6. Whey Lemonade - homemade lemonade that has whey in it is full of probiotics and is great for the flora in your gut. There are lots of good recipes for whey lemonade on the web.
7. Feed it to your chickens - while this probably won’t apply to a ton of people, for those of us who have backyard chickens whey is a great supplement for chicken feed as it contains a lot of protein. This is especially beneficial when chickens are molting
There are a ton of other ways to use whey, some of which I have tried and some which I haven’t. From chicken broth substitute, to a substitution for water when cooking rice/oatmeal/quinoa, etc, to skin moisturizer, it seems like whey can be used for just about anything. And it can be frozen and saved for a later date, which is just an added bonus.
All from a gallon of milk!
