Preparation

1. Roast tomatoes:

   Step 1

   Preheat oven to 400°F.

   Step 2

   Put tomatoes, cut sides up, in 1 layer in a 13- by 9-inch baking dish. Dot with 2 tablespoons butter and season well with salt and pepper. Roast in middle of oven until skins are wrinkled and beginning to brown, about 45 minutes. Cool in baking dish.

   Step 3

   Bring a large pot of salted water to a boil.

   Step 4

   Beat together eggs and ricotta in a large bowl with an electric mixer until blended. Stir in flour, 1 teaspoon kosher salt, and 1/2 teaspoon pepper until combined. (Batter will be soft.)

   Step 5

   Use 2 teaspoons (flatware, not measuring spoons) to form gnocchi: Scoop up a rounded teaspoon of batter, then use second spoon to scoop mixture off spoon and into boiling water. Make 9 more gnocchi.

   Step 6

3. Make sauce and sauté gnocchi:

   Step 7

   When tomatoes are cool enough to handle, peel and seed them over roasting pan. Slice tomato flesh lengthwise 1/4 inch thick and put in a medium saucepan. Scrape skins, seeds, and any juices from roasting pan into a fine sieve set over saucepan with tomatoes and press on solids in sieve to extract juices. Discard skins and seeds.

   Step 8

   Stir 1/4 cup water into tomatoes and bring to a low simmer over low heat. While tomatoes are coming to a simmer, melt remaining 2 tablespoons butter in a 12-inch nonstick skillet over moderate heat, then cook gnocchi, turning gently, until heated through, 4 to 5 minutes.

   Step 9

   Season gnocchi with salt and pepper and serve with warm tomatoes.
