What are some of your favorites?
I don't have one yet. I have tried a number of heirloom paste/roma tomatoes and most seem to miss the mark, according to my Italian lady friend.
Last year I switched and grew Johnny's Mariana F1 hybrid and the taste was there, but they were quite susceptible to early blight, despite being a hybrid. Very few of my heirloom tomatoes got early blight last year.
Some of the heirloom varieties I have tried and not been fond of are: Amish Paste, Cuor di Beu, Royal Chico and Mama Leone.
This year I am trying, San Marzano (heirloom) and Granadero (F1), plus a Red Pear Piriform.
A good sauce is paramount to my lady friend, so we are on a mission to find a favorite. :) I would like it to be an heirloom, so I can save the seeds.
After watching CountryBoy's YouTube channel I am quite interested in the Costoluto Genovese Heirloom Tomato. (hint, hint, wink, wink) :-D
