I do vermicomposting for my vegetable garden. One of the looniest things I do is make frozen worm food cakes.
Coffee from two coffee pods, actual worm food from the professional worm people, fresh whey from the yogurt I just made, and some frozen vegetable scraps.
Put all that in a Ninja blender and fill up the silicone molds and put that in the freezer for a few hours. Then I pull them out of the mould and into a freezer bag. I use these when I don't have more fresh stuff at the ready.
The proudest animal under the sun, and the wisest animal under the sun,—they have come out to reconnoiter.
