This year we planted a bunch of San Marzano "Italian" type tomatoes.
Yesterday my DH picked the first two apparently ripe ones. Both had
very firm flesh on the inside with almost no liquid or seed. And they
were at least one third hollow! In fact, the inside reminded me a lot
of a red pepper since it was so hollow. I have not seen this before in
any tomato. Does anyone know if this is a characteristic of this
particular tomato or some kind of growing problem? Our San Marzano
plants are just filled with unripe fruit--- more than I have ever seen
on any tomato plant of any variety. I have not tasted them yet. So
weird.....

I grew them once and they looked like the standard plum tomato. I
haven't any idea why the ones you grew are hollow. Or, maybe it's just
mine that were weird and you're are normal :-)
