Condiment culture

Condiments may seem simple, but, as chef Marcus Samuelsson writes in "New American Table," "they reflect who we are more than any other food."

Not only do condiments offer flavor, they contribute color, texture and aroma to any dish. And they can speak of culture and history. Take ketchup, that all-American dunk. It was created in Asia, with nary a tomato in sight, at least for a century or two. Here are some of the world's favorite condiments, the ones you'll find on the dining tables of each continent, and how you can use them in your kitchen. --Bill Daley
