Steps
Tap an underlined word for a quick explanation.
Fill a large pot with water, add the 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
While it heats, the lemon, then cut it in half and squeeze the juice into a small bowl, catching the seeds with your fingers.
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.
Dolly’s tip: Zest only the yellow. The white underneath is bitter.Finely the parmesan.
Grate. Grating means rubbing food across the holes of a grater to make fine shreds or flakes. It spreads cheese, garlic or ginger evenly through a dish so it melts right in.
How you’ll know: Even shreds fall off the back of the grater, and you stop while the piece is still big enough to hold.
Cook the spaghetti 1 minute less than the package says.
High heatTimer: 9 min
Meanwhile, the butter in a large over low heat. Stir in the cream and lemon and keep it warm, not 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.
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 heat
Scoop out 1 cup of , then the spaghetti.
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.
Add the spaghetti and ¼ cup to the and toss over low heat. Add the parmesan a handful at a time, , until it into a silky sauce.

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.

Low heat
Dolly’s tip: Low heat is the secret. If the pan is too hot, the cheese clumps instead of melting.Take the pan off the heat and in 2 tablespoons lemon juice and the pepper. Taste and add more juice or of salt until it tastes bright.

Pinch. A pinch is what you can hold between your thumb and two fingers, less than an eighth of a teaspoon. It’s a small, forgiving amount, so there’s no need to measure.
How you’ll know: It’s a light sprinkle you can barely see on the food, not a little pile.
Dolly’s tip: The juice goes in last, off the heat, so the cream stays smooth and the lemon stays fresh.Serve right away with torn basil on top.
