But I found an unlikely new source: the farmer's market. They occasionally have lamb kidney but that is now a hot food item. But they have a hard time moving beef kidney so I can pretty much get as much as I want. I've managed to score about 5 lbs. of lamb kidney total plus I can get cuts of lamb from them. I'll be asking them about pork and beef organs this week.
The co-op had a surprise emu order from the the original supplier in Montana. I was able to get 1 of the 5 cases of boneless emu scrap they were offered. Chance loves emu! It's a very dark red meat.
