Plum Tomato Sauce
Homemade plum tomato sauce using canned tomatoes.
You can use San Marzano tomatoes from Italy (such as Cento(R) brand) instead of plum tomatoes, if preferred. If you can find imported dried oregano from Italy, it will make a difference.
Some let tomato sauce simmer 'for hours,' but I haven't found that a longer cooking period increases flavor--what it does do is turn tomato sauce into a thick gravy, which isn't very appealing.
I like to process using a food mill over the sink so I don't make a mess. A food mill yields a great consistency for tomato sauce, and opens up the flavor of all ingredients. You can also use a food processor or blender, if preferred.
You can simmer the sauce covered for a thicker consistency.
