A tomato, fresh picked from your garden, sliced to wedges, a little salt and pepper!! The whole difference is home grown and picked perfectly ripe. I will agree with you that supermarket tomatoes are trash. They are picked early and too hard. Some places even chemically ripen them. That is trash. Get them from a fresh farmer stand, and you may well change your mind. The next 2 months are prime time.
I pick all the remaining tomatoes,, even the full green ones, just before the first frost, and ripen them in the basement under newspaper. They end up tasting like supermarket ones.
