Preheat about an inch (2 cm) of oil to 350˚F (180˚C) into a heavy, high-sided skillet or pan. Wrapping a freshly cooked burger can be a great way to improve its presentation. Serve with your favorite dip like salsa, sour cream. Fold the tortilla around the burger, like an empanada. Place a tortilla on a flat surface and place a patty in the center, cheese-side down. Divide cheese among all four tortillas, evenly. You can wrap a burger in wax paper, parchment, or foil to prevent juices and toppings from spilling out of the buns. Continue to work your way around, folding the flour tortilla over the center fillings. Well, when you fry, heat evenly surrounds the entire patty, keeping those crust-enhancing, protein-saturated fats (those tasty burger juices) inside the meat, where they belong. If there is a spot left open in the center, cut a piece of another flour tortilla and tuck it in the center, so it's fully covered. Brown the tortilla on both sides. One at a time, invert the burger, in its bun, onto the center of a tortilla and wrap the tortilla around it, making overlapping folds and using egg wash to hold down each fold. Place hamburger patty on top of cheese. Carefully wrap/fold tortilla around burger. As long as water vapor is escaping, oil can't penetrate the patty, so you don't have to worry about fat logging your burger… Flip and place on a sheet pan, seam-side down. Place burgers in the pan, fold side down. You can also wrap a burger in lettuce or a tortilla if you want to skip the bun. Cook over medium-high heat until tortillas are crispy and cheese is melted. (Or do two at a time if they don't all fit in the pan. Drain burger juice out of the pan and add four flour tortillas. Tabu, a new burger joint that opened in our Santa Ana, California neighborhood a few months ago, has a history of disappointment and pleasant surprises. Take off heat. Carefully flip tortilla wrapped burger and place on griddle/pan folded side down. The result should look something like a pentagon. Prepare bottoms and then tops.) To fold the crunch wrap, start with the bottom of the flour tortilla and fold the edge up over the center.
