For the past few months we've been getting a mushroom share from our CSA. Every other week we bring home about 2 pounds of oyster, lions' mane, and sometimes shiitake mushrooms, all grown locally. In addition to a lot of mushroom based meals*, I have been saving the trimmings with my other vegetable trimmings to make stock.
Today I made and canned nine pints of vegetable stock. We were running out, and the pantry needed replenishing. The addition of mushroom trimmings makes the stock darker, and it smells richer as well. I'm sure it will taste better, too.
I also made a pot of chicken stock, since I had everything out. That's in the fridge, so I can skim off the fat. Tomorrow I'll can that, too.
*In addition to the usual mushroom things (stroganoff, pasta, pizza), we have made mushroom steaks with the lions' manes, a mushroom scampi, and some glazed mushroom dishes. A lot of these recipes are coming from the NYT cooking app which is a tremendous resource of recipes. I'm not sure why I waited so long to subscribe.
