Passed by North Shore Kosher Bakery on Touhy today so I stopped in and bought a couple of Black and White cookies, their last two Black and White cookies at that. The counter lady said they usually make them on Monday, sometimes Tuesday, but had a few left from a special run yesterday. She also said they will make special runs for customers for as few as 6, though that seems low to me.
I've attached a picture of North Shore's Black and Cookie, the glaze was firm, not in the least sticky. Call to make sure they have B & W Cookies if you're making a special trip.
