Preheat pans and ovens fully
Steak, fish and vegetables dropped into a cold pan heat up slowly with it, leaking juice instead of browning. A pan hot enough to sizzle on contact browns the surface at once, and the crust lets the food release.
The beep comes before the walls are hot
The beep means the air reached your number. The metal walls, racks and baking stone are still cooler, and they need another 10 to 15 minutes. Until they catch up, every door opening dips the temperature.
Test yourself
Questions from the interactive lesson, with the answer and the why.
Your steak is stuck to the hot stainless pan after one minute. What should you do?
Wait until a crust forms and it lets go. Proteins grip the metal until the crust forms, and then the food lifts free.
True or false: When the oven signals it is preheated, its walls and racks are already fully hot.
False. The air reaches the set temperature first, while the walls and racks lag, so wait 10 to 15 more minutes.
What went wrong? You slide cookie dough in the moment the oven beeps. The cookies come out pale and flat.
The oven walls were still cool, so the heat was weak. The beep means hot air, not hot walls, and weak heat delays setting and browning.
Fill the blank: To get a crust before the inside overcooks, the pan must be ___ before the food goes in.
To get a crust before the inside overcooks, the pan must be hot before the food goes in. A hot surface browns the outside fast, before the inside overcooks.
You flick a few drops of water into a stainless pan. What tells you it's ready for a sear?
They bead into balls that skate across the surface. A vapor cushion lets drops glide above about 190°C (375°F), so the pan is ready.
