For the uninitiated, San Marzanos are a variety of plum tomatoes grown in San Marzano sul Sarno, near Naples, and are considered by many chefs to be the best in the world. In other words, they make your dinner taste like it was cooked by an Italian grandma.
But it?s not just professional chefs who can cook with them?it?s anyone whose grocery store carries them (they come in cans that look like this). As long as?dun dun dun?they?re not fake.
It turns out, tomatoes can be called ?San Marzano? without actually being grown in the Sarno Valley. And news flash: They?re just as expensive as the real ones, but they aren?t nearly as good.
To make sure you?re buying the real thing, check the label. If the can reads ?Pomodoro San Marzano dell?Agro Sarnese Nocerino D.O.P.,? you?re in the clear. If not, don?t expect your pasta sauce to taste quite as authentic.
The more you know.
