They’re cut with a knife

Some people believe that the perfectly straight fries are made using molds and fake potato goop. But since the fries are made with real potatoes, they are cut with a real knife. After the potatoes are skinned and washed, they are shot through a high pressure water tube at 60 to 70 miles per hour. The tube sends them to a series of blades that cut them into French fries.

By the way, this is how to get fresh McDonald’s fries every time you order.

They’re flash frozen before they get to the store

Before being packaged, the fries are dried, partially cooked and flash frozen. This maintains the color and crunch. They’re then sent out to McDonald’s franchises around the country.

There’s a reason they look just like the commercials

Have you ever noticed how the fries look particularly fresh after having been stored in the freezer? You can thank chemicals for that. After the fries are cut, they get covered in sugar so they are all the same color. Then, they’re coated in sodium acid pyrophosphate to keep them from turning gray when frozen.

These are the McDonald’s secret menu items you never knew about.

They have 19 ingredients

Well, technically there are only 14 individual ingredients; some are listed twice because they’re used in two different stages of production. Some of the ingredients include potatoes, canola oil, soybean oil, natural beef flavor, hydrolyzed milk and citric acid.

The secret ingredient that makes them so addictive

The real reason you can’t help but pull over to grab fries every time you see the golden arches: Beef flavoring. Yep, you read that right. McDonald’s has been adding beef fat to their fries since the 1950s. This practice has been updated to be a canola oil blend containing beef flavoring. This is to mimic the beef tallow that was originally used.

They’re not vegan or vegetarian

It’s no surprise that after learning the secret ingredient, you also find that McDonald’s fries aren’t vegan. Initially, McDonald’s fries were fried in beef tallow while other restaurants used vegetable oil. However, after switching to vegetable oil themselves, customers noticed a decline in taste. To ensure the great-tasting and recognizable flavor we all love, McDonald’s now uses a canola oil blend that contains beef flavoring.
