"I cook this way every night at the restaurant," says Isabelle Alexandre, "but it works just as well in an apartment kitchen."
A hot skillet creates a delicate, tasty crust. You'll heat the pan over a medium-high flame and use just a little bit of oil. The pan is hot enough when you see the bare beginnings of smoke. When you tilt the pan, the oil will look ripply. But I caution you, don't let the oil actually smoke: have everything right near the pan so you're ready to sear your ingredients the second your oil is hot enough.
To get that nice, brown crust, you'll need to leave the food alone in the skillet (no poking or nudging). But at the same time you need to make sure the food isn't sticking: here's where pan temperature is key. You can check by holding whatever you'll be cooking with a pair of tongs and touching one edge to the pan surface. If the pan is hot enough, the food will slide easily on the light film of oil. If it sticks, the pan needs to be hotter.
A very hot oven produces a juicy interior. You'll need to turn the oven on as soon as you start getting ingredients together so it has plenty of time to reach 500°F. As soon as the searing part is done, you'll flip the food over and transfer the skillet to the hot oven. By the time you close the oven door and wipe down the stovetop, it will be time to check if dinner is ready.
