If you buy the variety most often found in American grocery stores (usually labeled as Roma tomatoes), they're terrible. Try the variety labeled as "tomatoes on the vine" (four-digit produce code 4664, which I know from memory, having punched it in to so many self-checkout scanners over the years). They're actually juicy and tasty the way tomatoes should be. Avoid Roma tomatoes, they're cardboard masquerading as a tomato.

Truly great tomatoes must be fully ripened on the vine, where they'll continue to develop flavor and sweetness. Look for plump tomatoes, with the heft and give of a water balloon. If you have a choice, look for substantial and meaty heirloom varieties with balanced sweetness and acidity, like Cherokee Purple or Brandywine.

Avoid tomatoes that feel light for their size, which means they have more air pockets inside and are typically better for saucing or salads."
