When using canned tomatoes, I always choose San Marzano. They are a favorite for their sweet flavor and low acidity.  This variety of plum tomatoes are grown in the rich volcanic soil at the base of Mount Vesuvius. The flesh is firm and not too juicy; they are deep red in color with an easy to remove skin and low seed count. San Marzano canned tomatoes are considered a premium type, and there are several brands that carry them.
