Did you ever have a bland flavorless apple that tastes like recycled balsa wood?
That apple probably tasted that way because it had been sitting in storage somewhere for a long time.
If you don't know what is in season just check your local farmer's market or ask the produce guy at the grocery store.
Last month it was gravenstein apples and I just had a nice juicey Fuji. YUM!
Peaches and necatarines are on their way out but now comes apples and soon it will be tangerines.
If there is not a recent crop of local fruit available you can get some pretty good imported fruit. If it is not in season in the Northern hemisphere I look for fruit from the Southern hemisphere.
