So lately, I started wondering: what is the difference between peppercorn/ground pepper/black pepper (the stuff that you sprinkle on stuff) and peppers (as in: chili peppers, bell peppers, etc)? Are they fundamentally the same thing? Do peppercorns come from peppers, or is it the other way around? Are peppercorns the initial birth state of peppers?
And you know, speaking of peppers, what is the difference between ketchup and catsup? Is catsup composed of a different proportional mix of tomatoes and vinegar?
