I'm enjoying my tomato salad (tomatoes, salt, Sherry vinegar, olive oil, chopped Trinidad Yellow Seasoning pepper sprinkled atop), thinking to myself, DAMN that's a fine tomato. Tomande from Tomato Growers Supply. Very vigorous, very disease tolerant, set fruit at ninety degrees and is setting more at sixty degrees. Quick to ripen, too--maybe two weeks behind my cherries. Dark green shoulders. Sweet but a nice acidity to it, too. Honest, tomato flavor. Keep your heirlooms. I'll stick with this hybrid!
I've also been taking a box of Yellow Submarine tomatoes to work with me every day. Very sweet when completely ripe, nicer when a little greener. Thin enough skin. Good vigor, early, open-pollinated to boot.
