I know I am painting with a broad brush here. If you are one of the minority who has some produce savy I give you the kudos you deserve. Most supermarket fruit sucks. Thats just the sad truth. It is picked early, and immature, so that it ships and displays well.
Taste is a very low priority.
Retailers count on eye appeal to sell produce. You have to learn to shop with all off your senses to pick good fruit. We live in a world of instant gratification. People want to be able to buy strawberries year round. The result of that mindset only reenforces the need for fruit that ships well.
