but you'll find that while a vegetable is in season you can't beat the taste and texture of the real thing.
Just for a different point of view: This, and similar comments, add up to the biggest myth in the food world. iEven in season, whether or not the taste and texture improve depends on where and when the vegetable was grown.
If you grew it yourself, and just went out in the yard and picked it, everything said about fresh is true.
If you bought it at a growers-only farmers market, and the veggie was picked just yesterday (or possibly even this morning) and brought directly to market, also true. That is, in fact, the focus of the whole locovore movement.
However, if you're buying at a supermarket or other such store, frozen can actually be better in the same way that FAS fish can be better than "fresh."
It has to do with the nature of the food distribution system, and the simple fact that most markets, at least in North America, do not source locally at all, or do so only to a minor degree---which leads to such anomolies as, at the height of sweet-corn season, the boxes at the supermarket saying "product of Mexico."
There are other considerations. When I worked for Package Engineering magazine there was a study done that compared the total value of vegetables. Fresh, canned, and frozen were compared for quality and taste, and for their contribution to the solid waste disposal problem. The report from the organization performing the study wryly noted: We did this study in the summer. Would have liked to have redone it in the winter, but only two of the three forms were available."
That's not an unimportant consideration. Given a choice between a vegetable that was grown 2,000 miles away, and subjected to the abuses of the food-distribution system, on one hand, or the same veggies harvested, prepped, and flash frozen within hours, which really has the best flavor, texture, and nutritional value?
