There are two kinds of spaghetti nights: the ones that taste fine, and the ones that make you quietly stop chewing like, wait, why is this so good? This is the second kind.
We are going for soft and chewy noodles (not mushy, not stiff), plus a sauce that clings like it means it. The trick is not fancy ingredients. It is timing, starchy pasta water, and a quick emulsified finish that turns a basic sauce into something glossy, rich, and borderline decadent.
Keep it relaxed. Taste as you go. And if you hear yourself say, “Okay, wow,” mid-bite, that is the recipe working as intended.
