Spaghetti with Shrimp and Tomato Passatina

Serves 4-6

Extra virgin olive oil

1/2 yellow onion, finely diced

3 garlic cloves, minced

1 carrot, cut into 1/4-inch pieces

1 pound shell-on raw baby shrimp

Kosher salt and black pepper

A pinch of dried red pepper flakes

1/2 cup white wine

1 1/2 cups canned tomatoes

4 breadsticks, like grissini, broken up

2 teaspoons chopped parsley

12 ounces fresh spaghetti or dried

1. Heat a thin film of olive oil in a large, wide pot over medium heat.

2. Stir in the onion and sweat until softened, 3 minutes.

3. Stir in the garlic and sweat 1 to 2 minutes more until aromatic.

4. Add the carrot and sweat until softened, 3 to 4 minutes.

5. Turn up the heat to medium-high, stir in the shrimp, and season with salt, pepper, and pepper flakes.

6. Pour in the wine and bring to a simmer.

7. Stir in the tomato and return to a simmer.

8. Pour in 1 cup of water, lower the heat, and cook for 8 to 10 minutes or until the shrimp are soft enough to break up with a wooden spoon if pressed.

9. Stir the broken grissini pieces into the pot, remove from the heat, and stir in the parsley.

10. Place a food mill fitted with a coarse plate over a clean pot.

11. In batches, pass the shrimp and broth through the food mill. You will have a coarse paste. (If it's too dry to go through the food mill, stir in more water).

12. Taste the shrimp paste and season with salt and pepper.

13. Bring a pot of salted water to a boil.

14. Cook the spaghetti for 4 minutes if using fresh, and as directed on the package if using dry.

15. Drain the spaghetti, reserving a cup of pasta water, and return the spaghetti to the pasta pot.

16. Stir spoonfuls of the shrimp paste into the spaghetti until evenly coated, adding a few spoonfuls of water if the pasta looks dry, and simmer for one more minute before serving.
