If you eat them before they get too ripe they do have a very fruity sweet taste, with just a touch of tomato tang. If you let them get beyond firm ripe the taste is rather bland. I read that if your refrigerate them until chilled they have a somewhat cherry taste. I have not tried that yet.
I have had no problems with disease or cracking. They are a very pretty, smooth tomato skinned tomato.
Which one did you grow this year?
