Why Draining Your Pasta In The Sink Is A Big Mistake - Tasting Table

"If you're one of those cooks who drains their pasta straight into the sink without a second thought, you're not alone. But, did you know that you're letting liquid gold swirl away? Yup, that cloudy water you're tossing out is far more valuable than it looks. Pasta water is loaded with starch, and it can transform your sauce from flat and watery to silky and restaurant-quality, so it's a secret weapon in your culinary armory."

"When pasta cooks, it releases starch into the boiling water. This starchy water becomes thick and cloudy, which might not look appealing, but it's exactly what your sauce needs. It acts as a natural emulsifier, helping oil and water-based ingredients like butter, olive oil, tomatoes, and cheese, bind together. This gives your sauce a luxurious texture without having to add flour, cream, or thickeners. In short, it turns a collection of ingredients into one cohesive, velvety sauce."

"Beyond texture, pasta water also helps flavor cling to the noodles. Have you ever had pasta where the sauce just slides off, leaving a pool at the bottom of the bowl? That's often because there's no binder to bring everything together. A splash of starchy water in your sauce helps it stick to every noodle, from spaghetti to penne. It's the difference between eating plain pasta with sauce and a true Italian-style dish where every bite is infused with flavor."

Pasta releases starch into its cooking water, producing a thick, cloudy liquid rich in starch. The starchy water acts as a natural emulsifier, binding oil and water-based ingredients such as butter, olive oil, tomatoes, and cheese to create a silky, cohesive sauce without adding flour or cream. A splash of reserved pasta water helps sauces adhere to noodles, preventing sauce from sliding off and ensuring consistent flavor on every bite. Reserving a cup or two before draining and adding it while tossing pasta with sauce adjusts consistency, improves emulsification, and can also enhance soups, stews, and beans.
