Steps
Tap an underlined word for a quick explanation.
Put the rice and water in a small and over high heat.
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.
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.
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.
High heat
Cover, turn the heat to low and cook for 15 minutes, then leave it covered off the heat.
Low heatTimer: 15 min
the oven to 375°F. Stand the peppers upright in a baking dish, a sliver off the bottoms of any that wobble.
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.
Trim. Trimming means cutting off the parts you don’t eat, like stem ends, tough bits or thick fat. It keeps chewy or bitter bits out of the finished dish.
How you’ll know: What’s left is the good part, with no dry ends, woody stems or thick white fat.
Heat the oil in a large over medium heat and cook the onion for 5 minutes, until soft. Add the garlic and for 30 seconds.
Skillet. A skillet is a frying pan: wide and flat with low, sloped sides. The shape lets steam escape, so food browns instead of stewing.
How you’ll know: It’s the pan you’d fry an egg in, and a 10 or 12 inch one handles most recipes.
Stir. Stirring means moving food around with a spoon or spatula so it cooks evenly and doesn’t stick. Unless the recipe says constantly, every so often is plenty, and it gives food time to brown.
How you’ll know: When you drag the spoon across the bottom, nothing is sticking or scorching.

How you’ll know: When you drag the spoon across the bottom, nothing is sticking or scorching.
Simmer. Simmering means keeping a liquid just below a boil, with small bubbles rising gently. It cooks food evenly and lets a sauce thicken without scorching on the bottom.
How you’ll know: Small, lazy bubbles break the surface every second or so, and nothing is churning.

Pack the filling into the peppers and pour the rest of the tomato sauce around them in the dish.
Cover with foil and for 30 minutes, until the peppers are tender.
Bake. Baking means cooking in the oven with dry heat all around the food. It cooks evenly from every side, so you can mostly leave it alone.
How you’ll know: It’s golden on top and passes the recipe’s check, like a clean toothpick or the right temperature.
Timer: 30 min
Dolly’s tip: A knife should slide through the side of a pepper with no crunch.Uncover, top with the rest of the mozzarella and 10 minutes more, until and bubbling.

Melt. Melting means gently heating something solid, like butter or cheese, until it turns liquid. Low or medium heat keeps it from browning or burning.
How you’ll know: It’s smooth and liquid, and butter may foam a little but hasn’t turned brown.
Timer: 10 min
Dolly’s tip: They keep 3 days in the fridge. Reheat covered at 350°F for 20 minutes, or in the microwave.Food safety: Rotisserie chicken, deli meat, canned tuna and cooked shrimp are already cooked. Keep them cold until you use them, and heat them until steaming hot if the recipe warms them.
