Wondering what to do with spoiled milk? Don’t throw it a-whey! While your initial reaction may be to get rid of sour milk, a tastier and more sustainable option is using it to make homemade cheese.

Fresh milk quickly turns sour if you don’t use it – especially unpasteurized milk. Although it’s no longer drinkable, you don’t necessarily have to throw out spoiled milk: it has plenty of household uses. You can use sour milk to descale faucets or as an overnight soak to bring back the shine to your silverware. You can even use spoiled milk in the kitchen, as a base for homemade cheese

For this recipe, you’ll need a total of eight cups of whole milk (3.25%). It doesn’t have to be sour milk: you can use however much sour milk you have and top the rest off with fresh milk. Or, you can even make the whole recipe using fresh milk – it’s up to you! You’ll also need a cheesecloth or a thin dish towel to make this cheese. 

Note: We recommend buying organic milk products whenever possible. Organic farms adhere to stricter standards than conventional producers and practice species-appropriate animal husbandry. If you want to know exactly where your milk comes from, look for regional suppliers at local farmers’ markets.

Spoiled Milk: Recipe for Homemade Cheese

Ingredients:

  • 2 cups sour cream
  • 4 medium eggs
  • 1 tbsp salt
  • 8 cups (sour) milk

Preparation:

  1. Add sour cream, eggs and salt to a bowl and mix until combined. 
  2. Pour the (spoiled) milk into a pot and heat it slowly over low to medium heat. As soon as it starts to boil, reduce the heat and slowly stir the sour cream and egg mixture into the sour milk.
  3. Continually stir the mixture until small white clumps begin to form (approx. 6-10 minutes). This shows that the milk protein is separating from the whey – in other words, the milk is curdling.
  4. Leave the pot on the stove for another 10 to 15 minutes, stirring constantly.
  5. Now it’s time to separate the milk protein from the whey: take the pot off the stove, wet the cheesecloth and place it in a sieve. Then pour the contents of the pot through the cloth. Tip: Place a container under the sieve so you can collect the whey and use it later as a brine.
  6. Wrap the cheesecloth tightly around the milk protein (careful, it’ll be hot!) and squeeze out as much of the remaining liquid as possible. Let the tightly wrapped cheese cool at room temperature.
  7. Place the cloth with the cheese mixture in a bowl and refrigerate for at least four hours. 
  8. Unwrap the cheese, serve and enjoy!

Note: Store the finished cheese in an airtight container in the refrigerator. It is best to cover it with brine or with the collected whey – this way it will keep for about a week to ten days.
