Homemade Cottage Cheese

Discover a simple way to repurpose your sour milk by making homemade cottage cheese – it’s easier than you might imagine! This process requires only a few basic ingredients: at least 2 liters of sour milk, 6 tablespoons of white vinegar or lemon juice, and 6 tablespoons of heavy cream. To begin, simply bring the milk to a boil in a saucepan, then remove it from the heat source and carefully stir in the vinegar.

As you wait for the mixture to cool, you’ll notice that the curds will start to separate from the yellow whey – allow this process to complete over the next 30 minutes. Next, line a colander with cheesecloth and gently strain the mixture, allowing it to drain for approximately 5 minutes before gathering up the cloth and giving it a gentle squeeze until all excess liquid is removed.

Once you’ve extracted as much of the whey as possible, you can either use the cheese as is or mix in some heavy cream to give your cottage cheese an extra-rich flavor.
