True.. cows milk is more tough.
My family had its own CSA growing up. Grandma's sister keep Jerseys. She churned it for butter and buttermilk and we drank it raw. Still remember the smell of wild scallions in the milk in Spring. Grandpas uncle butchered hogs that we salt cured and made sausage. Huge garden. Our cellar looked like a preppy organic food store. Shelves of canned tomatoes, bean, etc., pickled corn in urns, dried beans, fruit. Really miss those days and the food. Gosh I'm hungry!
