Can a tomato be a celebrity? Ask the San Marzano Tomato—if you can get past its bodyguards. One commercial grower proclaims it the “gold standard for taste.” Martha Stewart devoted an entire blog post to it. Certified tomatoes from Italy are regulated. It even has its own Wikipedia page. But at the end of the day, it’s still just a tomato.
