"Michel Bras purees this lush mushroom soup with bread toasted to a dark brown to thicken the texture and deepen its flavor. He learned the trick from his mother growing up in the Aubrac mountains, one of France's poorest regions. "I used to mix bread crumbs with sugar for a little treat," Bras says. "We were happy with very little."..."
