A TikTok video uploaded by one claiming to be a McDonald's employee that shows how the restaurant's classic Big Mac is made amassed over 1.9 million likes and 6.9 million views.
The TikTok account called @essentialmcdonalds has more than 638,000 followers who watch its videos for glimpses into the McDonald's kitchen.
According to the TikTok user, employees use separate toasters to warm the three buns, dubbed the "crown," "club," and "heel."
The crown and heel are the top and bottom buns, while the club refers to the middle bread piece.
Each piece of bread is toasted on each side before being transferred to a square take-out box.
The video said that employees should add one shot of Big Mac sauce to the club and the heel but instead used three squirts per bun.
A handful of dehydrated onions and around a half-ounce of lettuce are added onto the club and heel pieces. Then two pickles were placed onto the club while a cheese slice goes to the heel before adding two pieces of patties.
The TikTok user noted that the "most challenging" part of making a Big Mac is transferring the now-assembled club portion on top of the heel.
