This post sure made me hungry. For me, the defining moment of the garden is picking that first ripe tomato. I like one that will cover my whole sandwich , and slice it about an inch thick....and enjoy.
I have 2 varieties you should try. One is called Big Beef, and was an all american selection winner a few yrs back. It has a lot of resistance to diseases and cracking, and is the kind you can slap on a big sandwich and cover the whole thing.
A second one for just popping in your mouth is another all american winner called Juliet Hybrid. It is looks like a small version of a roma , slightly bigger than a cherry or grape tomato. It is one of the best tasting tomato varieties you can get (imho) for just eating whole or on salads. I gave a few of these plants to the neighbors when I first tried them, and they quickly became one of their favorites. You don't plant many of these (they are big producers)....but just great to have so everytime you stop by the garden you grab a few and eat right on the spot. Sometimes when they are ripening, it is hard for me to mow by the garden...as I will make a round, then stop and eat a few, then mow another round or 2 and stop and eat a few more...and they are kinda addictive that way.
I've been known for going a little overboard on tomatoes. One year I ordered probably 40 - 50 different varieties of tomato seeds, and raised plants, to test them to see which I liked best. I had over 100 planted in the garden. The ones named by others are all good. Everyone says brandywine has the best taste, but I find that it cracks easily ...which is a common problem with many of the big varieties.
If you are into making paste, or ketchup.... I've found the heirloom variety Amish Paste, to be great. It is larger and meatier than a roma , and has a very good taste.
Ok, that was my 2 cents worth....
