Ina Garten-Inspired Lemon Capellini

Compiled by Igor Kukolj, Editor. Nobody here has cooked this — how these are made.

Four ingredients, ten minutes, and one of the ingredients goes down the sink in most kitchens.

The cloudy water the pasta cooked in is full of released starch, and that starch is what binds butter and lemon juice into a sauce. Fat and acid do not combine on their own; the starch granules sit at the interface and hold them together, the way an egg yolk does in a hollandaise. Without it you get melted butter and lemon juice sitting separately on the noodles, which is what most home versions of this dish actually are.

Take a mugful out before you drain. You will use most of it.

Capellini cooks in about two minutes

Angel hair is thin enough to go from raw to overcooked while you turn around. It also keeps cooking in a hot pan of sauce. Pull it a full minute before the packet says, get it into the pan, and finish it there.

Zest into the butter, juice at the end

The oils in the zest are what smell of lemon; they need fat to dissolve into, and they go into the melting butter. The juice is acid and it dulls with heat, so it goes in at the very end, off the heat. Two parts of the same fruit doing two different jobs.

Toss hard, and keep adding water

The sauce comes together through agitation — the tossing is what emulsifies it, not the heat. It will look thin, then suddenly turn creamy. If it tightens or looks oily, another splash of pasta water and more tossing brings it back every time.

Storing

Eat it immediately. Capellini in a butter sauce is not a leftovers dish; it goes soft within the hour and there is no way to revive it.
