Colander

A colander drains; a sieve strains. The holes in a colander are large enough to let water through fast and small enough to hold pasta, and that is a different job from separating solids out of a liquid you want to keep.

Colander against sieve

Colander
Large holes, rigid bowl, feet or a stable base. For draining pasta, potatoes, washed vegetables and tinned pulses.
Sieve
Fine mesh. For straining stock and sauces, sifting flour, and anything where you want to keep the liquid and lose the solids.
Chinois
A very fine conical sieve. For genuinely smooth sauces and soups.
Both, ideally
They are cheap and they do not substitute for one another. A sieve drains pasta slowly and a colander lets a sauce straight through.

What makes a good one

Beyond draining

Looking after it

The pasta water rule

The most common colander mistake has nothing to do with the colander: it is tipping the pasta straight into the sink and losing the cooking water.

Pasta water is starchy and salty and it is what turns a sauce into something that clings — see how to cook pasta. Once it is down the drain, no amount of stirring will produce the same result.

The habit worth building is to put a mug in the sink before you drain, or to lift the pasta out with tongs and leave the water in the pan. Either works; the second is what most professional kitchens do.

Common questions

Should I rinse pasta after draining?

No, except for a cold pasta salad. Rinsing removes the surface starch that helps sauce cling.

Can I use a colander to steam?

Yes, over a pan of simmering water with a lid, provided it fits without touching the water.

Metal or plastic?

Metal, for durability and because boiling water does not warp it. Plastic is fine and quieter.

Why does mine drain so slowly?

Too few holes in the base, or the food has formed a mat over them. Shake it.
