Pasta lovers are often guilty of draining their pasta water down the sink before adding sauce. But there is an important reason to save your pasta water and it is pretty scientific. Because pasta is made of flour, it releases starch into the cooking water as it boils, creating a white, cloudy liquid that emulsifies sauces it is added to. Emulsification is the process of blending two liquids that would otherwise repel each other ― in the case of pasta, it’s oil and water ― into a smooth, inseparable mixture.

This makes for a better sauce, so if you ladle some pasta water out before draining the rest you are going to be giving serious chef vibes. With that said, it is time to impress everyone you ever cook for again - just from the simple act of saving a small bit of water. Have your say in our news democracy.
