The Difference Between Foods

The difference between fruits and vegetables depends on whether you are talking to a botanist or a cook, but Daven at Today I Found Out gives us a decent short course in telling the difference. He also explains the difference between jelly and jam, kosher salt and table salt, and the different colors of pepper. What blew my mind was the difference between green olives and black olives. I thought they were different kinds of olives! Personally, I much prefer the taste of green olives. (Thanks, Daven!)
