I get a little frustrated when I hear the phrase from snooty chefs on Food Network say that I should buy "what's in season."
"What IS in season you dolt?! Not all of us have that information or know where to go get it." I knew eggplants were in season in the summer from the Alton Brown "Good Eats" episode on eggplant.
When I go to the store, the produce looks pretty good. I buy it. I'm not paying too much attention to prices from June to now.
Apparently, Food Network heard me screaming, and they now have a handy-dandy guide to what is in season.
