Which sauce was invented first?

Thousand Island was placed on the menu at the Waldorf-Astoria Hotel back in 1894. After the maître d’hôtel forgot to dress the salads, they improvised by quickly throwing together a range of ingredients together that were available.

Fry sauce first appeared in 1900 featuring in a New Orleans cookbook. However, it wasn’t until Don Carlos Edwards added the sauce to his Arctic Circle fast-food chain in 1940 that it gained popularity.

How are the sauces used?

Both sauces are most commonly used as condiments to dip hot potato fries, vegetable sticks, cheese sticks, and other fried foods.

Across the world, Thousand Island is by far the most popular sauce of the two. It can replace Russian Dressing, spread between corned beef and cheese to make a delicious Reuben sandwich.

Thousand Island gained notoriety as the secret sauce in the McDonald’s Big Mac. Other diners and fast food chains like In-N-Out Burgers also use it as a secret sauce.

When fry sauce isn’t being consumed with cheese sticks or fries it is often served with twice-fried plantain slices, called tostones. It is also found next to appetizers such as lumpia.

Fry sauce gained popularity at Arctic Circle and is now found in chains like Freddy’s, Zaxby’s, and Raising Cane’s. Each food venue has created subtle variants of the original recipe – they have also branded their name on the sauce.

Where to find Thousand Island dressing and fry sauce

Thousand Island and fry sauce can both be purchased as retail products from grocery stores in the sauce aisle. If you can’t find any near your location, a quick search online will provide plenty of options.

If you live in Utah, you probably already know that fry sauce is available in practically every restaurant – each business has its own recipe. The sauce is also found in parts of Oregon and southern Idaho, but isn’t as popular in other parts of the U.S.
