Where can I buy (in NYC) whole fat buttermilk? I can only find the lowfat, 1 1/2% milkfat version, usually the Friendship or Tuscan brands. Please, no guesses, I'd like to limit my search to confirmed sightings only.
Relatedly, what are peoples' opinions of the canned buttermilk powder? I'm guessing that it's better to use fresh lowfat buttermilk than reconstituted canned solids but if someone can educate me on this topic I would appreciate it greatly.
