The classic burger has gone from humble beginnings (as a simple hamburger sandwich brought over to the States by German immigrants) to become an enduring symbol of modern fast-food culture. But now these popular patties are enjoying a renaissance with the arrival of the gourmet burger and its little cousin the ''slider'' (mini burger). High-quality burgers, made with organic ingredients and bold flavourings are topped with inspired new takes on mayos and relishes and presented in freshly-baked artisan buns and rolls. Mouth-watering recipes to try in this book include Classic Restaurant Burgers with Bacon, Cheese and Pickles; Mexican Burgers with Homemade Guacamole and Fresh Tomato Salsa; Lamb and Feta Burgers with Homemade Tzatziki; Root Veggie Burgers with Fresh Guacamole; Pork and Caramelized Apple Sliders; and Beef Sliders with Mozzarella Pearl Centres in Mini Ciabatta.
