I like knowing where my food comes from and enjoy hobnobbing with growers at farmers markets. Now I can learn where my milk comes from, and you can too, just by typing some numbers into the handy little website whereismymilkfrom.com. From full-fat cow's milk to goat milk, from whipping cream to cottage cheese, you simply type in the code and learn the dairy where the milk was produced.I was able to easily identify where a gallon of milk I picked up at Target was from, but couldn't locate the smaller dairies for my organic milk. The dairy codes were just nowhere to be found on the carton. Some codes on milk jugs can be hard to identify, but the website walks you through many coding variations. So grab your yogurt container and find the source of your dairy.
