Craving a Big Mac? You can now buy one at the local grocery store.

Of course, you will have to put it together yourself. But McDonald’s has put together an instructional video showing how to make its signature burger with ingredients you can pick up on your own.

We’ve long known what goes into a Big Mac. If you were around in the mid-1970s, you no doubt remember the jingle that lists what goes into the tasty treat: Two all-beef patties, special sauce, lettuce, cheese, pickles, onions on a sesame seed bun.

McDonald’s Canada put out a video this week that shows the company’s executive chef, Dan Coudreaut, making a Big Mac in his home kitchen.

According to a story in the Los Angeles Times, the video resulted from a campaign undertaken by McDonald’s Canada to answer questions asked by customers on its website.

In what the Daily Mail referred to as a “warm and fuzzy PR stunt,” Coudreaut removes his white chef’s jacket and announces that he is going to “be a little less formal” because “we’re just gonna have some fun cooking."

He starts out making the “special sauce,” the formula for which he admitted was revealed on the Internet a few years back. He mixes mayonnaise, sweet pickle relish, classic yellow mustard, white wine vinegar, garlic powder, onion powder and paprika in a bowl.

Then he quickly dices an onion, slices the top half of the bun in two, cuts up lettuce, makes two burgers from ground beef and grills them up in a frying pan on his stove, adding some salt and pepper after flipping them.

“This is 100 percent beef, just like in our restaurants,” he announces.

Then he toasts the bun and constructs the sandwich.

Chances are, yours won’t look quite like those in the McDonald’s ads, which are dressed up by “food stylists” before they are ready for their close-ups, the Daily Mail explained.

But if they taste the same, what’s the difference?
