And a nice enameled roasting pan with lid (actually the cheap kind I got at Walmart for a cooking emergency once)
Saute a couple of minced garlic cloves in olive oil. I singed them again but decided that would work. Throw is a few handfuls of chopped celery and the lamb on medium. Once the lamb was browned I added ~8 cloves garlic, some more celery, half a large onion (in big chunks), those 3 potatoes cubed and then the mushrooms just cut in halves. I tied a bunch of fresh oregano, rosemary, thyme and sage up and put that in (mostly rosemary). Then wine (1/2 cup?) And enough water to come 1/2 way up and some salt. I let that come to a boil then turn it down and put the lid on and left it to simmer for a couple of hours. I added more red wine and water as needed to keep the liquid up. I stirred it every now and then.
When all ingredients were tender I made basic bisquick (yes, a cheat) for about 12 biscuits and patted handfuls to about 3/4 inch thick and covered the stew. Baked at 400 until top turning "golden brown". It needed a little more salt at the table which is how I like things.
Served with a nice spring salad.
