The Bakery produces 1 Bread (difficulty 5) out of 2 Flour and 1 Fuel.

A Bakery produces 1 Bread in 13 ticks (1 tick to fetch flour + 1 tick to fetch fuel + 10 ticks to bake (+10% per tick) + 1 tick transport the bread), while a Kitchen produces 1 Bread in 27 ticks (+3.75% per tick) and a Workshop produces 1 Bread in 67 ticks.

That makes bread production in a Bakery about 2 times faster than a Kitchen and 5 times faster than a Workshop.
