The workshop cause quite a lot of parings and sawdust should be protected with dustproof cover.
Two interesting parings with chardonnay were the Manzanillo with oregeno and an unusual but beautifully textured black olive (this is layered in with rock salt and baked for an hour).
Middlings, warm water, apple parings, meat gravy, carrot scrapings, meat scraps, stale hominy, and the wrapper off a package of cheese.
