Fast food misfires come in many forms. Mindless mashups, ill-conceived holiday homages and irreconcilable departures from a restaurant’s primary offerings are just a few of the ways fast food chains around the world have embarrassed themselves and disgusted their customers. Here are ten of the most ridiculous culinary concoctions in fast food history. Bon appetit.

The Double Down Sandwich (KFC)

This winter, mired in the third wave of the COVID-19 pandemic, the people of Italy received a true treat from the US military: assistance with vaccine procurement and distribution.

Actually wait – scratch that. The American soldier was Colonel Sanders, and the gift was a triple bypass to top off that deadly respiratory disease. On February 15, 2021, the Double Down Sandwich returned to KFCs across Italy, giving our parmesan-eating brethren a taste of the American heart(attack)land. What’s the Double Down, you ask? Well it’s pretty simple: take two fast food favorites – bacon and cheese – add something suspiciously called the “Colonel’s Sauce,” and put it all between… two gigantic slabs of Original Recipe fried chicken. The Double Down pretty much exemplifies America’s willingness to take pride in gluttony. It caters to the growing (and growing, and growing) set of US consumers who gleefully shun sound medical advice in the name of freedom. Hell, the very name suggests that its ingestion is a gamble. Incredibly, the Double Down is only 540 calories – about as much as a McDonald’s Big Mac. However, the devil (and the diabetes) lies in the details: 145 milligrams of cholesterol (more than twice the Big Mac), 1,380 milligrams of sodium (over half the recommended limit) and 32 grams of fat (half the day’s allowance). Per metrics site FiveThirtyEight, the result is one of the unhealthiest sandwiches ever.

Buffalo Latte (Tim Horton’s)

Throughout the 2010s, beloved Canadian coffee & donut chain Tom Horton’s had its sights set on expansion in the U.S. Americans familiar with the chain – generally considered higher quality than Dunkin’ but less expensive than Starbucks – welcomed Timmy H’s with open arms and wallets, and today there are over 500 locations across the US.

But in October 2017, Tim Horton’s forced a square idea into a round donut hole. To celebrate openings across Buffalo, NY – the birthplace of buffalo sauce – the company introduced an absolutely repulsive buffalo-flavored latte. Two hypotheses exist concerning this limited-time menu monstrosity. The first posits it was simply a bad idea; that a coffeehouse which also offers a variety of breakfast sandwiches could have honored Buffalo with a buffalo-flavored sausage, egg & cheese biscuit (or, at the very least, something that wasn’t milky… definitely a gross-out line crosser).The other theory is that Tim Horton’s never intended to sell a single cringe-inducing cup of the Buffalo Latte, but instead was engaging in a publicity stunt. While making potential customers gag isn’t typically recommended, there’s a bit of buffalo-flavored brilliance to that.

Kit Kat Chocoladilla (Taco Bell)

Let’s be honest: an entire list could be dedicated just to Taco Bell items. In fact, one already is.Not surprisingly from the marketing geniuses who decided the “Fourth Meal” should be a thing, there’s a lot to digest (or indigest) here. Potential candidates for Taco Bell’s top spot include the why-is-a-taco-joint-doing-this triangular chicken chips with nacho dipping sauce, the idiotically named Beefy Potato-rito, and the entirely appropriately-named Forbidden Burrito. But Taco Bell saved its best dietary disaster for last. Its Kit Kat Chocoladilla boldly asks the question “why not top off your fourth meal with a chocolate sandwich?” Basically, picture a large soft tortilla slathered with Nutella-esque chocolate sauce, interspersed with chocolate chips and chunks of Kit Kat bars. If you believe the officially stated calorie count of 329, I have a chocolate-covered, tortilla-wrapped bridge in Brooklyn to sell you. Men’s Health magazine took a matter-of-fact perspective toward the Kit Kat Chocoladilla, deeming it in line with Taco Bell’s penchant for TexMex-bastardized trial and error: “it’s about time they smashed a candy bar and chocolate chips between two halves of a flour tortilla. That whole fried-chicken-as-a-taco-shell thing,” the review continues, referencing another culinary experimen
