Method
- In a medium saucepan, whisk the tomato passata and tomato paste into the hot water along with the salt. Set over low heat and keep it just below a simmer. This is your broth — it must stay hot the entire time you cook the pasta.
- Place the cast-iron skillet over medium-high heat and add the olive oil, crushed garlic cloves, and chili peppers. Let them sizzle for about 1 minute until fragrant but not browned.
- Ladle in about 1 cup of the hot tomato broth. It will hiss and bubble aggressively. Let it spread evenly across the skillet.
- Lay the dry spaghetti flat into the skillet, like logs across the tomato broth. Do not stir or break the strands. Press them gently into the liquid with tongs so they begin to soften and bend.
- As the strands soften, fan them out in a single layer across the pan. Let them sit undisturbed for 2 to 3 minutes so the bottoms toast against the iron. You should hear a continuous crackle.
- Flip the pasta with tongs in sections, exposing the toasted side. Let the new side sear for another 2 minutes.
- Ladle in another half cup of hot tomato broth. Let the spaghetti drink it in without stirring much. Continue this risottata method: sear, add broth, sear again.
- Repeat the process for 15 to 18 minutes total, adding broth every couple of minutes as the pan dries out. Allow the strands to stick and char in spots — those black flecks are the soul of the dish.
- Taste a strand. It should be al dente with a smoky, almost burnt edge and a thick, clinging tomato glaze. If still firm, add one more small ladle of broth and cook 2 minutes more.
- Drag the spaghetti into a tight nest with the tongs, press it against the hot iron one last time for 30 seconds to crisp the bottom, then slide directly onto warm plates. Eat immediately while the crust still crackles.
