What is the best method for boiling tomatoes to prepare a delicious tomato sauce?

The best method for boiling tomatoes to prepare a delicious tomato sauce is to first score the bottom of each tomato with an "X" and then blanch them in boiling water for about 30 seconds. After blanching, transfer the tomatoes to an ice bath to cool. This will make it easier to peel off the skin. Once peeled, chop the tomatoes and simmer them in a pot with olive oil, garlic, onions, and herbs until they break down into a thick sauce.
