Seashells with Basil, Tomatoes, and Garlic

Raw tomatoes become juicy when they are infused, which contributes to the preparation of the sauce.
Combine the oil, garlic, and 3/4 tsp salt in a large bowl. Slice 1 cup tomatoes and add to the bowl. Cut the remaining tomatoes in half and toss with the mixture; let stand for about 30 minutes, stirring occasionally.Meanwhile, cook the pasta as directed on the package in a large pot of salted boiling water.Drain the pasta, reserving 1 cup of water. Combine the pasta with the tomato mixture, then the cheese and all but 1 tablespoon of basil. If necessary, add a little water for the paste to make it more friable. Sprinkle the remaining basil on top and season with salt.
