Using Cooking For Blockheads 1.15.2-8.0.1 I am finding the kitchen multiblock is not registering the cow in a jar. With a jar full of milk on a countertop, the cooking table recipe book does not show any milk-based recipes.

I was able to make a chocolate bar, but I cannot make a Simple Farming wheel of cheese. So the multiblock does see the cow in a jar, just not all recipes work.
