I haven't tried the meat yet, but I just saw a sign at the Wishing Stone farmers market (Tuesdays, off Wickenden St in Providence). It said they're now selling beef and lamb from Treaty Rock Farm (I think that was the name) in Little Compton. It was $7.50 a lb. I'm trying to clean out my freezer this month, so I passed on it this time (unprecedented grocery restraint), but I can't wait to try it, and thought I'd pass on the tip.
Are there other sources of grass-fed, local meat or poultry in Providence?
