… it’s about whipping cream and why it goes stiff and other stuff. By the way, you could always use the saved buttermilk from your homemade butter to start a sauerkraut culture.

Why was I whipping cream? Because berries are in season and I eat berries that are in season. Does my weight go up with the extra sugar load? Yes it does.
