Now, let it simmer for at least 15 minutes. Don't rush. If you boil it hard, you'll kill the subtleties and end up with atomic red lava. Simmer means tiny, happy bubbles—like a Jacuzzi for flavor dwarves. Taste it after 10 minutes. Add salt, pepper, and if it's too tart, more sugar. If it's too sweet, more salt. You are the balance deity now.
Here's a miracle: add a tablespoon of unsalted butter at the end. Not olive oil—butter. Stir it in off the heat. The fat smooths out the rough edges and makes the sauce feel like a hug from a millionaire grandmother. Trust the butter. It’s not dairy; it’s liquid silk.
The Secret Weapon: Fish Sauce
Okay, lean in. You’re at a café, I’m being funny, but this is serious: a tiny splash of fish sauce (like half a teaspoon) will change your life. It doesn't taste fishy—it adds a savory depth called umami that makes people moan involuntarily. If you’re a vegetarian, use soy sauce or miso. But fish sauce is the nuclear option. I once put it in a sauce for a vegan, they didn't know, and they cried because it was "the best sauce ever." I'm a bad person, but a great cook.
Another wild fact: Kraft actually makes a tomato paste-based sauce that they call "pizza sauce." It's just paste, water, and sugar. You're officially making the same thing, but with soul, garlic, and moral superiority.
