Why save pasta water?
Pasta water, in one line
Pasta water is the starchy, salty water left after boiling pasta, and a splash helps a sauce thicken, cling, and turn silky instead of oily.
Why it works
As pasta cooks, it releases starch into the water. That starch acts as a thickener and emulsifier, helping fat and water in the sauce bind into a smooth coating that clings to each noodle. The salt in the water also seasons the dish. Adding a little at a time lets you reach the perfect consistency.
How to do it
Common mistakes
- Forgetting to save it before draining, which is the most common mistake.
- Using too much water at once, which makes the sauce thin.
- Using too much water in the pot, which leaves the pasta water thin and less starchy.
