I don't even count it. As for calories, I couldn't even begin to guess. Everybody makes theirs a little differently, and every batch is going to vary widely.
I make it, let it cool off and pour it into freezer trays and freeze it, extra goes into jars to thaw later to reload the trays. Might eat one or two cubes a day, toss them into my greens. The fat stays on top, frozen. I do simmer it down when making it, try to reduce the water content way down so it is more dense, easier to store, etc.
Steak, eggs, potatoes - fruits, nuts, berries and forage. Coconut milk and potent herbs and spices. Tea instead of coffee now and teeny amounts of kelp daily. Let's see how this does! Not really had dairy much, and gut seems better for it.
