You'll be amazed that anything this simple could taste so good, not to mention that all this garlic—yes, two heads, not two cloves—can produce such a seasoned, mellow taste.
Cooks' notes:
·If ripe tomatoes are not available, substitute 1 (28-ounce) can whole tomatoes in juice (not in purée; preferably San Marzano), chopped, including juice; season sauce with sugar if desired.
·Sauce keeps, chilled, 4 days.
