Humidity versus Steam
All the "artisan baking" (I know the adjective is "artisinal," Mike!) books I have provide instructions for humidifying the oven to approximate the function of steam injectors in professional bread ovens. Some recommend using ice cubes. Some recommend hot water. Some recommend humidifying the oven before putting loaves in. Others humidify after loading the loaves.
I think it is Maggie Glezer in her recipe for Dan Lepards Country French Bread who recommends putting ice cubes in a pan before loading to "humidify" the oven and putting hot water in a skillet after loading the oven to "steam" it.
Can anyone comment on this procedure and clarify 1) the difference between humidifying the oven and steaming the oven, 2) the difference in the timing of adding water (in whichever form) on oven spring and crust formation?
And, has anyone tried the garden sprayer method Glezer recommends? If so, does it really yield a different result than throwing hot water into a hot skillet?
