Dear Heloise: Recently, I was looking through a cookbook and found a recipe, only to notice that one of the ingredients listed was plum tomatoes. What is this? I have heard of cherry and grape tomatoes, but not plum. – Annette in Texas

Annette, we took your question to the California Tomato Commission, and here is what it had to say: Plum tomato is another name for a roma tomato.

And don’t refrigerate tomatoes. Tomatoes should be stored at room temperature but not in direct sunlight. One note: If you buy tomatoes that have been refrigerated, then they really should be refrigerated once you get home. – Heloise
