‘Secret’ ingredient in McDonald’s world

‘Mud’ drinks and ‘greens powders’: Here’s what you need to know about these trending wellness drinks

“When our suppliers partially fry our cut potatoes, they use an oil blend that contains beef flavouring,” McDonald’s website said. “This ensures the great-tasting and recognisable flavour we all love from our World Famous Fries. The fries are cooked in our kitchens, seasoned with salt, and served hot to you.”

McDonald’s Canada, McDonald’s UK and McDonald’s Australia, however, do not utilise beef flavouring in the cooking of their fries, Howlett said.

While some commenters claimed the fast food fact is already common knowledge, Howlett’s TikTok video had accrued over 10.8 million views in less than a week as many commenters shared their surprise at the secret ingredient.

“I actually already knew that one!” one commenter said. “Had to learn that when I was vegetarian and found out I’d been eating cows via McDonald’s fries.”

“Good to know (because) my son’s allergic to beef,” another commenter said.
