Boil the milk. When choosing milk, raw or pasteurized milk may be used. Ensure that you are not using ultra pasteurized milk. Begin by boiling 1 gallon of whole milk to 170°-190°F and stir as the milk heats up.
Once the milk reaches it’s temperature of 170°-190°F, slowly pour in coagulant, or ½ cup and 2 tablespoons of white distilled vinegar. Ensure you are mixing while slowly pouring the vinegar. The vinegar will act as a coagulant and separate the curds from the whey.
Next, pour out the separated curds and whey into a cheese cloth to strain out the whey. You can keep the whey in the fridge for other recipes such as for soups, baking, or for cooking grains (rice, quinoa, or oats). Squeeze the curds to ensure all of whey liquid is out.
Salt to taste and begin the fun part – the molding. I typically will mold to a circular glass bowl to obtain the aesthetics of commercially sold queso fresco.
