Ingredients

15 ripe plum tomatoes 

Coarse salt 

1 tablespoon sugar, for dusting 

1/4 teaspoon crushed red pepper, flakes 

2 cloves garlic, thinly sliced 

2 tablespoons extra-virgin olive oil 

Preparation

Preheat oven to 200 degrees. Line two baking sheets with parchment paper and set aside.

Bring a large pot of water to a boil; meanwhile, prepare an ice-water bath. With a paring knife, core tomatoes, and score an X on the bottoms. Working in batches, carefully lower tomatoes into boiling water; when skins begin to split (30 to 60 seconds), use a slotted spoon to transfer tomatoes to ice water.

When tomatoes are cool, peel and halve lengthwise. Using a spoon, scoop out seeds and discard. Place tomatoes on prepared baking sheets and season with salt, sugar, red pepper flakes, and garlic. Drizzle with olive oil and transfer to oven. Cook until tomatoes are bright red and sweet, 4 to 5 hours.
