Ronnybrook Farm makes some. Ronnybrook is at lots of different farmer's markets throughout the city, including Saturday in Union Square. They also run the Milk Bar in Chelsea Market, but I don't know if they sell farmer's cheese there.
Wow. That's good to know. I buy all sorts of stuff from Ronnybrook at Friday's greenmarket (UWS) but I never knew they sold farmer cheese. I'll add that to the yogurt, milk, butter, yogurt cheese, creme fraiche list. Thanks for the info.
