Serves 4

Ingredients

1 onion, sliced

1 lb well-marbled short ribs

1/2 tsp marmite

1 tsp tamari soy sauce

1 tsp Worcestershire sauce

1/4 tsp truffle salt

1 tbsp anchovies (not anchovy paste)

1/2 tsp bonito flakes

1 pinch of Harissa

1/4 cup grated Parmesan cheese

4 slider buns

1/2 tbsp butter

Tomatoes and lettuce, for toppings

Directions

1. Cook onions in oil over low heat until caramelized, about 15-20 minutes.

2. Grind the short ribs in a meat grinder and set aside.

3. Combine marmite, tamari soy sauce, Worcestershire sauce, truffle salt, anchovies, bonito flakes, and Harissa in a mortar and grind together using a pestle to form a paste.

4. Add the seasoning paste to the grounded short rib meat and mix gently until evenly distributed (don't overmix). Fold in the grated Parmesan cheese to the meat.

5. Form 4 oz. patties and cook in a pan, or on a grill, about 3-4 minutes each side so it's medium or preference of doneness.

6. In a small pan, add butter and toast buns.

7. Assemble umami sliders with the buns, patties, caramelized onions, tomatoes, and lettuce.
