Umami Burgers Recipe

I call these “umami burgers” because they are seasoned with a touch of fish sauce and topped with mushrooms—both wonderful sources of umami. Umami is the fifth taste, after sour, salty, bitter, and sweet. It is usually described as the “savory” taste. Umami’s amazing savory taste is produced by ribonucleotides, molecules that help boost flavor naturally in many foods, including beef broth and aged cheeses. These burgers are topped with bone marrow, providing that creamy mouthfeel that we crave without dairy. The bone marrow also packs a huge nutritional punch!
