I can always tell when carrots are in season. It's in the sweet clear taste and how easily that outer ring breaks away for the core.
I love raw tomatoes, but only in season. Out of season, they're sad little crayon approximations that want ot grow up to be a real tomato.
For a long time, I thought I'd lost my taste for chicken. Then I realized that real chicken, that hasn't been cooked to death and has seen the outside world, tastes AWESOME.
