Try this dimpled, chewy, herb-topped deep-dish focaccia
Centuries ago, focaccia began as a by-product: When bakers needed to gauge the heat of the wood-fired oven — focaccia stems from focolare and means “fireplace” — they would tear off a swatch of dough, flatten it, drizzle it with olive oil, and pop it into the hearth to bake as an edible oven thermometer.
