What Can You Do With “Expired” or Sour Milk? Don’t Toss It Yet!

b. Pet Treats
Mix a small amount of sour milk into your dog’s or cat’s food as a treat, but ensure it’s still safe and hasn’t gone too far beyond its expiration date.
When to Toss It?
If the milk has a rancid smell, curdles excessively, or shows signs of mold, it’s time to discard it. But in most cases, slightly sour milk can be a goldmine of utility.

Before you toss out that expired milk, consider these eco-friendly, creative uses. From cooking to gardening, sour milk can serve a second life, saving you money and reducing waste!
