preheat high bake low
pardon my ignorance but what exactly does it mean to preheat high but bake at lower temp, e.g., preheat to 500F but bake at 450F? does it mean...
1. set oven thermostat to 500F, wait for thermometer inside the oven to reach 500F, place bread in oven, close oven door, set thermostat to 450F
2. set oven thermostat to 500F, wait for thermometer inside the oven to reach 500F, place bread in oven, keep oven door open while waiting for thermometer to go to 450F then close oven door, set oven thermostat to 450F
3. set oven thermostat to 500F, when oven beeps and preheat light goes off (thermometer inside the oven not yet at 500F) place bread in oven, close oven door, set thermostat to 450F
sometimes a recipe says preheat to 500F, bake for 10 minutes, lower temperature to 450F, same question for that. my confusion is whether i should actually lower the ambient temperature in the oven or does "lower temperature" simply mean turn down the oven thermostat setting and leave it alone.
i'm guessing this might be what's causing my baking mishaps with rye and whole grain breads. i have no trouble (usually) with white crusty breads which are baked on steady temps such as 450F.
