Spaghetti All'Assassina

Instructions

1. Whisk water, tomato paste, and sugar in a saucepan. Bring to a simmer over medium-high heat, then reduce to low to keep warm.
2. Heat 1/3 cup olive oil, garlic, and red pepper flakes in a 12-inch nonstick skillet over medium until garlic is golden, about 2 minutes. Stir in tomato passata and salt; cook until thickened, about 4 minutes.
3. Add spaghetti in an even layer and increase heat to medium-high. Add tomato broth 1 cup at a time, cooking and pushing between strands until mostly absorbed before adding the next cup, about 20-25 minutes total.
4. Increase heat to high and cook without moving until the underside is deeply browned and crisp with some charred strands, 3-5 minutes. Drizzle with remaining 2 Tbsp olive oil and serve immediately.
