KENJI'S BETTER BIG MAC

Steps:

• PATTIES.
• Pass beef through meat grinder fitted with 1/4-inch plate twice. Form into 2 even balls and flatten into 4-inch patties using wet hands against a cutting board.
• Scrape patties up with thin spatula and place on a sheet of parchment paper. Refrigerate until ready to use.
• Place the 1/4 cup minced onion on a double layer of paper towels on a microwave-safe plate and microwave for 10 minutes on LOW power (setting 1 or 2) until mostly dehydrated, but not browned. Set aside.
• SAUCE.
• While onion is dehydrating, combine grated onion, mayonnaise, relish, mustard, sugar, marmite and turmeric. Stir to combine and refrigerate until ready to use.
• BUNS.
• Preheat toaster oven or broiler to high.
• Use one finger to spread a very thin layer of egg white over the top of the top bun. Sprinkle with sesame seeds and place under the broiler for 30 seconds until set. Set aside.
• Use a sharp, thin knife to cut off the very bottom of the bottom bun half, creating a single circular piece of bread with cut surfaces on both sides.
• Toast cut side of top bun and bottom bun, and one side of center bun piece under broiler until light golden brown.
• BEGIN ASSEMBLY AND COOK PATTIES.
• Place bottom bun and center bun on cutting board toasted-side up.
• Spread half of sauce on each.
• Divide dehydrated onions evenly between bottom and center buns and top with lettuce. Place 2 pickle slices on each.
• Season burger patties with salt and pepper, to taste.
• Heat a heavy-bottomed 10-inch stainless steel or cast iron skillet over high heat until lightly smoking.
• Add patties and cook WITHOUT MOVING until first side is crusty and browned, about 1 minute.
• Scrape up patties with a stiff spatula and flip.
• Top 1 patty with 1 slice cheese.
• Continue cooking until cooked through, about 1 minute longer.
• Transfer cheese-topped patty to bottom bun and cheeseless patty to middle bun.
• Place top bun on top of center, then stack center bun on top of bottom.
• Serve immediately.
