Why Are Burgers and Fries Commonly Served Together?
I’ve asked myself the same question a while back. There isn’t much literature on the subject (the well documented ones already build on a culture of burgers and fries) but a number of reasons come to mind.
Burgers are finger-food. To serve something with them that requires utensils would be counterproductive to the idea of “on-the-go eating.” So, in the starch group, only fried potatoes remain.
Fries go well with the condiments and sauces used on burgers. Ketchup, mayonnaise, even mustard, are commonly used with fries; in the UK, vinegar based sauces are also in heavy rotation.
Fries are easily made and – like the burger – are low-involvement finishers. That means they can be pre-made to a close proximity of finish and take about as long to be done as a meat patty on the grill.
