A game for you: What is that thing in the above photo?
Some background, and a clue: I had never heard of this device before but it came up in a conversation I recently had with a friend. He was telling me about this Italian bakery in San Francisco that’s known for its homemade foccacia. Family-run Liguria’s in North Beach is so popular that people, young and old, are already lined up when it opens in the morning, cash in hand. By noon, all that still-warm bread made in their 100-year-old oven is sold out. Anyway, they make use of this device with every purchase. That’s your clue.
Give up? This is what it is and I bet you’ll be able to tell how Liguria’s uses it. Also, I checked: you can still buy this thing!
