OK, I've got it now. It's called tomato tartare even though it's cooked, because it LOOKS like beef tartare. Those French are sneaky, aren't they? Kind of like calling wishbones, Grenouillettes, because they LOOK like froglegs. I'll wait until my tomatoes get ripe because the recipe said use only the best. I'll post a photo.Thomas Keller has a famous tomato tartare.
