I'm looking for grass fed beef tendons and grass fed osso bucco, either locally or online. Does anyone know anyplace that sells them? I've tried asian markets, which I'm guessing aren't selling grass-fed, and I've had to use them in a pinch, but they don't consistently carry it every time I need them. I know Marin Sun Farms has them, but they unfortunately don't have an online shop, and I live a distance from SF or Berkeley. Any suggestions would be appreciated!
