Editor's note: The recipe and introductory text below are from Rick Tramonto's book Fantastico! I unabashedly love beef tartare and yes, this is my favorite crostini, particularly because I gild the lily with a drizzle of truffle oil! Steak tartare has been around for a good long time, and according to legend, its name refers to the Tartars, the nomads who roamed eastern Europe, for a time under the leadership of Attila the Hun. Fierce and bloodthirsty, the Tartars purportedly ate raw meat for strength. Tartars were Huns, but "beef hun" just doesn't have the panache of beef, or steak, tartare. If you've never had beef tartare, try it my way; then make it your way by omitting what you may not like such as capers, Worcestershire sauce, or anchovies. But don't fool with the beef. Buy the best you can from a reputable butcher. I use prime beef when possible, but because it is sometimes hard to find, I may turn to high-quality choice beef instead.
