Yesterday I made ghee in the oven by cooking sweet butter for 2hrs in the oven at low temp. I filtered the resulting liquid through cheese cloth and let the resulting clear liquid sit overnight.
Today, the ghee has congealed into a solid, as it should. However, on top of it is an oily liquid. I poured some into a glass and added water, and the two liquids don't mix, so it's not water left over from the butter (good news). Still, I'm confused why I don't end up with a uniform material.
