Spaghetti with Fresh Tomato Sauce

The dish has a thick creaminess that you can never duplicate with canned tomatoes, no matter how good they are. So the season when you can make it—when there are good, ripe tomatoes in the market—is fairly short; where I live, just two or at the most three months a year. There is an ideal instant for serving this sauce: When the tomatoes soften and all of their juices are in the skillet, the sauce suddenly begins to thicken. At that moment, it is at its peak; another minute or two later, many of the juices will have evaporated and, although the essence of the sauce is equally intense, it won’t coat the pasta as well. If this happens, just add a little fresh olive oil or butter to the finished dish.
