The science: why this works
Why pasta water helps the sauce
Cooking water holds starch from the pasta. Stirring a few tablespoons into the peanut butter loosens it into a smooth sauce, and the starch helps the sauce cling to the noodles. Tossing the pasta with the sauce over low heat lets the two bind into one dish.

Peanut butter is rich and fatty. Lime juice adds acid that cuts the richness and keeps the sauce from tasting heavy. Soy sauce adds salt and savory depth. Tasting at the end lets you nudge the balance with a pinch of salt or a drop more honey.
Learn: Balancing salt, sweet, sour →Why the pasta water is salted
Pasta absorbs water as it cooks, so salted water seasons it from the inside. Unsalted pasta tastes flat even with a bold sauce. The water should taste lightly salty, like a mild broth. Salt added to the sauce alone cannot season the pasta itself.
