RICK BAYLESS CLASSIC TORTILLA SOUP
Rick Bayless Classic Tortilla Soup
Earthy dark pasilla chile (sometimes called negro)... its unique flavor defines tortilla soup in central Mexico. In Michoacan, in west-central Mexico, it's ancho chile. In your kitchen, it might turn out to be another chile, like New Mexico or even a little smoky chipotle (be forwarned that chipotle will make the broth quite spicy).
