PET Milk is a brand of evaporated milk that has been around since 1895. Evaporated milk is a shelf-stable canned cows milk product where about 60% of the water has been removed from fresh milk. It differs from condensed milk, which contains added sugar. PET Milk is used in many different recipes, from main dishes to soups, desserts, and more. It is a convenient substitute for milk and can be used in equal amounts for recipes that call for milk. PET Milk can be stored in the refrigerator for 2-3 days after opening, and for best flavor and quality, unused portions should be placed in an airtight container. PET Milk should not be used as a baby formula, as it does not have the proper nutritional values infants need for their digestion and growth. PET Milk is owned by Eagle Family Foods Group, which still produces and sells the product today.
