Part 3/7:
While the burger patties chill, it's time to prep the toppings. Canel recommends keeping it simple with garnishes such as thinly sliced red onions, fresh tomatoes, and cheddar cheese—though any cheese will work as long as it melts well. Additional options include iceberg lettuce and pickles. For a standout flavor, Canel prepares a homemade burger sauce combining mayo, ketchup, mustard, and relish. This sauce can be made in minutes and is enough for four burgers; simply double the recipe if making eight.
