Twenty or so years ago I worked in a neighbor's tomato packing shed. For commercial use he had his pickers gather the "breakers"-tomatoes just beginning to go from green to beginning to ripen. We were allowed to gather all the vine ripened tomatoes we wanted and take home. The vine ripened tomatoes were delicious, but the few breakers I took home and ripened on the windowsill were the rubbery, tasteless variety. There were the same tomatoes off the same vines. Like Trapper, I'm a little prejudiced about Arkansas tomatoes, but the real trick is allowing them to ripen on the vine. I guess that's why commercial tomatoes are generally lacking in flavor, they are picked too green so they can be shiped and stored.
