the oven to 450°F.
Preheat. Preheating means turning the oven on before you start, so it’s fully hot when the food goes in. Food that starts in a cold oven cooks unevenly and doesn’t brown the same.
How you’ll know: The oven beeps or its light clicks off, usually 10 to 15 minutes after you turn it on.
the rice and bring it with the water and ½ teaspoon salt in a .
Rinse. Rinsing means running cold water over rice or canned beans in a strainer while you swish them around. It washes off loose starch and can liquid, so rice cooks up fluffy and beans taste clean.
How you’ll know: The water running out goes from cloudy to mostly clear; it doesn’t have to be perfect.
Bring to a boil. It means heating a liquid on high until it’s fully boiling before you move on. A lid on the pot gets it there faster, which makes it a good moment to chop something.
How you’ll know: Big bubbles break all over the surface, and they keep coming when you lift the lid.
Saucepan. A saucepan is a pot with tall, straight sides and one long handle. It’s for things that need depth, like rice, sauces or a few boiled eggs.
How you’ll know: The food fills it about halfway, leaving room to bubble without spilling over.

Toss. Tossing means gently lifting and turning food so everything gets coated, like pasta in sauce or vegetables in oil. It coats every piece evenly without mashing anything.

Sheet pan. A sheet pan is a flat metal baking tray with a low rim all the way around. The rim catches juices, and the wide surface lets food spread out and brown.
How you’ll know: Everything fits in one layer with a little space between the pieces.
Roast. Roasting means cooking in a hot oven, around 400°F to 450°F, usually spread out on a sheet pan. The dry heat browns the outside and brings out sweetness, especially in vegetables.
How you’ll know: The edges are browned and a little crisp, and a fork slides easily into the thickest piece.
