Large black tomato?

[kevn357]

My Mother in law goes to a csa weekly and she brought home a massive black tomato but doesn't know the variety. It was at least 24 ounces. I figure I'll email the farm and hopefully they will tell me what it is and try to get some seeds.

I was just curious what everyone's largest black tomato was. All the blacks of tried (not many) have been medium sized but taste fantastic. My dad also loves the taste but likes LARGE tomatoes for some reason. So i'm curious if this large black tomato from the csa is something rare or are there a few large black heirlooms out there.

Thanks for any help.
