History

This day was created by Richard Ankli of Michigan’s Ann Arbor back in 1977. Richard created the date to honor his friend who had the last name ‘Sauer’ and since then, the date has gone from strength-to-strength, with so many people embracing it!

Sourest Day is now to celebrate all the sour things in the world, and while sour attitudes are included in this, sour foods have got to be one of our favorite things, and believe us when we say there are more than a few different options when it comes to sour foods.

Shall we start with the natural, off-the-vine, and out of the ground ones? We shall!

Oranges are actually considered a sour fruit (in part because of the high Vitamin C content) and are one of our favorites!

Limes are a bit sourer on the sour chart, and go great in a variety of drinks and on tacos, and then there’s the mainstay of summertime drinks and hot cups of tea, lemons! Of course, none of these have a thing on the incredibly delicious but mouth-puckeringly sour rhubarb, best served snapped straight off the ripe plant.

Then of course we have sour cream, buttermilk, and the delicious pickled cabbage that is sauerkraut. But none of these hold a candle to those most evil creation of our sour-loving kin, the sour candies.

For those with a mild tolerance for sour, there’s a joy to be had in the Sourpatch Kids candies, gummy candies covered in crystalline citric acid, the same thing that makes Lemons sour.

But Sourpatch Kids are just the start, and for those true connoisseurs of sour, there’s the Warhead candies, a candy so powerfully sour they actually had to reduce how sour they were during their original run! Now that’s sour!
