History Traditional wheat bread from the island of Madeira, with a round, flat shape, has always been much appreciated by Madeirans. The story goes that Bolo do Caco was baked on top of a shard of basalt, which is why it got its name. 16th-century charters forbade the construction of private ovens and the population had to pay to bake their bread in the ovens of the King, the Great Lords or the Religious Orders. As it was a bread that didn't need an oven to be baked, Bolo do Caco could be produced by the entire population, even in the humblest of homes. With no need to pay for its baking, its peculiar production became widespread.
