Steps
Tap an underlined word for a quick explanation.
Cut off the dark green tops and the roots of the leeks, them , and them.
Halve. Halving means cutting something into two equal pieces. Even halves cook at the same speed, so one doesn’t dry out while the other finishes.
How you’ll know: The two pieces look like mirror images of each other.
Lengthwise. Lengthwise means cutting along the long side, from stem to tip, which gives long pieces. Crosswise is the other way, straight across the middle, which gives short, round ones.
How you’ll know: Lengthwise halves of a zucchini look like two little canoes; crosswise pieces look like coins.
Thinly slice. Thinly slicing means cutting slices about an eighth of an inch thick, roughly two coins stacked. Thin slices cook in seconds and soften fast, which quick dishes need.
How you’ll know: A slice bends a little when you hold it by one edge, and slow, steady cuts beat fast ones.
Put the slices in a big bowl of cold water and swish them around to out the grit. Lift them out with your hands, leaving the dirt behind.
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.
Dolly’s tip: Leeks hide sand between their layers. Lifting them out, not pouring, keeps the grit in the bowl.Fill a large pot with water, add 1 tablespoon salt, cover and over high heat.
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
the butter with the oil in a large over medium-low heat. Add the leeks and ½ teaspoon salt and cook 10 to 12 minutes, stirring often, until very soft.
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.
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.
Low heatTimer: 11 min
Dolly’s tip: No browning here. Soft and sweet is what you want, so turn it down if they start to color.Stir in the garlic and thyme for 1 minute, then add the broth and cream and 3 minutes.
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.
Medium heatTimer: 4 min
Meanwhile, cook the pasta until , tasting 2 minutes before the package time. Scoop out 1 cup of , then .
Al dente. Al dente is Italian for “to the tooth”: pasta cooked until tender but with a slight firm bite in the center. It holds up in sauce and keeps softening a little after you drain it.
How you’ll know: Bite a piece a minute before the package time: tender, with a slight firm bite in the middle and no crunch.
Reserve pasta water. It means scooping out a cup of the starchy cooking water before you drain the pasta. A splash helps the sauce cling and turn silky, and it’s the step everyone forgets.
How you’ll know: A mug of cloudy water is sitting by the stove before the pasta goes into the colander.
Drain. Draining means pouring off liquid, like tipping pasta into a colander or spooning extra fat out of the pan. Pour hot grease into a can or jar, not the sink, where it hardens and clogs the pipes.
How you’ll know: Only a few drips are left, and the food isn’t sitting in a puddle.
High heatTimer: 10 min
Add the pasta, lemon , 1 tablespoon lemon juice and the parmesan to the leeks and , loosening with until creamy.
Zest. Zest is the thin, colored outer layer of citrus peel, rubbed off on the smallest holes of a grater. It holds the fruit’s fragrant oils, so it adds bright flavor without the sourness of juice.
How you’ll know: You see bright flecks and smell citrus right away; stop when you reach the white layer, which is bitter.
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.
How you’ll know: Every piece looks glossy or evenly coated, with no dry spots hiding underneath.
Reserve pasta water. It means scooping out a cup of the starchy cooking water before you drain the pasta. A splash helps the sauce cling and turn silky, and it’s the step everyone forgets.
How you’ll know: A mug of cloudy water is sitting by the stove before the pasta goes into the colander.
Low heat
Taste, add salt or more lemon if it needs it, and serve with the pepper.
