Pour the whey into the soup pot. Bring it to a boil, then reduce the heat until the whey stays at a gentle boil. Stir it with the spoon. Let the whey simmer until it becomes thick. When the whey has the consistency of caramel or fudge, spoon it out of the pot into the pan or onto the wax paper.

Step 2

Let the slab of whey dry for several weeks. Place a light cheesecloth over the whey to allow air to flow through but prevent flies and dust from landing on the whey. If you have a dehydrator, place a 1/4 inch layer of whey onto the fruit leather sheet in the dehydrator and dehydrate it for several days to speed up the process.
