The primary ingredient in traditional steak tartare is raw beef, typically from cuts like tenderloin or sirloin. Steak tartare is a dish that consists of finely chopped or ground raw beef served with various seasonings and accompaniments, such as onions, capers, Worcestershire sauce, and sometimes a raw egg yolk on top. The dish is often served cold and is appreciated for its rich flavor and unique texture. While popular in French cuisine, steak tartare has variations in other countries and is considered a delicacy, requiring high-quality, fresh meat for safe consumption and optimal taste.
