Of course, the hamburger phenomenon has long since become an international one, and culinary cultures from all over the world have proven keen to put their stamp on this classic dish. The Mexican burrito burger is a favourite with two possible interpretations. One: Use a traditional burger setup, with a well-seasoned patty and unmistakably Mexican toppings ranging from sour cream and refried beans to coriander, salsa, avocado and chipotle dressing. Alternatively, some chefs take the concept to the next level by slicing the ingredients lengthways and replacing the bun with a soft corn tortilla. Burger heavyweights from the East include the sushi burger and the ramen burger. To make the first, sticky, sesame-studded sushi rice is moulded into bun shapes and then filled with iconic sushi ingredients including fine cuts of salmon or raw tuna, avocado, ginger and cucumber. Don’t forget the wasabi and soy sauce; then ditch the chopsticks and use your hands to enjoy this delicacy! Ramen burgers replace the rice bun with moulded noodles. To get the perfect contrast of succulent and crispy textures that defines this dish, cook the noodles first, then blend with beaten egg, cool, shape and pan fry. Voilà!
