My regular bake went off without a hitch till just before the buzzer went off and my wife said, "You left the oven on convection!"..., Yep! The oven was at 450 dF AND convection. Flinging the door open half expecting to see a charcoal loaf revealed one of the most perfectly baked loafs I've ever done. What's more the crust had the depth and chewy crunchiness so admired in SFSD bread.
