  • Yield: 26 burgers 1x

Description

“As a chef, I love using fresh ingredients to create delicious and memorable meals for my guests, friends and family. For this reason, I choose to use mushrooms when cooking not only for their delicious flavor, but also because I feel that I have a responsibility to preserve our food source by incorporating sustainable ingredients like mushrooms. I am a blenditarian because blending mushrooms with wagyu beef allows me to create a healthy, delicious and sustainable burger.” – Chef Amir Hajimaleki

Instructions

  1. UMAMI MIX: In sauté pan over medium heat, cook butter until it turns brown in color. Add onions and sauté until translucent. Mix in mushrooms and sauté until tender and cooked down, about 5 minutes. Add thyme, mirin, sake, soy sauce, garlic and ginger, and simmer on low heat until excess liquid is absorbed. Transfer to sheet pan and let cool in refrigerator.
  2. JAPANESE ISLAND SAUCE: Place all ingredients except for rice bran oil into food processor. Gently pulse ingredients while slowly pouring oil through the feed tube. Continue to mix until the sauce has a smooth, velvety consistency.
  3. BURGER: In a large bowl, combine the ground beef and Umami mix until well incorporated. Divide mixture into 6-ounce patties and grill to desired doneness. Once cooked, place patties onto fresh, toasted Hawaiian bistro buns. Top with Japan Island Sauce, pickled bok choy, sliced cucumber and Délice de Bourgogne cheese.
