I always figured ice cream was just dessert. Then I found out the United States military once considered it so essential to winning a world war that the Navy commissioned an entire barge that did nothing but make it. That sent me down a rabbit hole, and it turns out ice cream has a resume that includes presidential proclamations, White House scandals of flavor, and actual neuroscience. Here are five true things about ice cream that made me look at my freezer with newfound respect. And since July is officially National Ice Cream Month, the timing could not be better.


Did you know the Navy built a floating ice cream factory during World War II?

In 1945, the U.S. Navy spent roughly one million dollars, real 1945 dollars, on a concrete barge whose entire job was making ice cream for sailors in the Pacific. It had no engine and no weapons. It had to be towed from place to place. What it did have was serious dairy firepower: the floating factory could churn out about ten gallons of ice cream every few minutes and store more than 2,000 gallons at a time, keeping the fleet supplied one ship at a time. Why the extravagance? Morale. The military had cut off beer rations at sea, so ice cream became the thing sailors fought homesick misery with. The Navy did the math and decided a million-dollar dessert barge was a bargain. Honestly, hard to argue.

Did you know WWII bomber crews churned ice cream in the sky?

Sailors were not the only ones improvising. Airmen figured out that a bomber at altitude is basically a giant ice cream machine: freezing temperatures outside, constant engine vibration inside. Crews would mix up canned milk, cocoa, and sugar, seal the mixture in ammunition cans or buckets, and strap them into the rear gunner’s compartment before a mission. By the time the plane touched down, the cargo had been shaken and frozen into a passable batch of ice cream. Command mostly looked the other way, because when your job is flying combat missions over the Pacific, nobody is going to begrudge you dessert. It remains history’s most heavily armed ice cream delivery service.

Did you know brain freeze has an official medical name, and a cure?

That stabbing headache when you eat ice cream too fast is called sphenopalatine ganglioneuralgia, which is medically accurate and completely impossible to say while experiencing it. Here’s what’s actually happening: when something very cold hits the roof of your mouth, blood vessels there rapidly constrict and then dilate, and the nerves in your palate send an alarm through the trigeminal nerve, the same nerve that serves your face. Your brain misreads the location of the signal, so you feel the pain in your forehead instead of your mouth. It’s a false alarm, filed to the wrong address. The fix is wonderfully low-tech: press your tongue flat against the roof of your mouth to warm it back up. The headache typically retreats in seconds, leaving you free to make the exact same mistake again.

Did you know Dolley Madison made ice cream a White House sensation, and one popular flavor was oyster?

At James Madison’s second inaugural ball in 1813, First Lady Dolley Madison wowed guests by serving up a grand ice cream spread, with a magnificent pink strawberry creation as the centerpiece. Ice cream had been enjoyed by earlier presidents, but Dolley turned it into an event, and she’s been linked with American ice cream lore ever since. Now for the part that will haunt you: one genuine flavor of that era was oyster ice cream. Early American cooks made ice cream out of whatever was abundant and fashionable, and in the Chesapeake region, that meant oysters, churned into a savory frozen cream. Parmesan ice cream was another documented favorite of the period. So the next time someone calls pistachio adventurous, you may inform them that their ancestors ate frozen shellfish for dessert on purpose.

Did you know July is officially National Ice Cream Month, by presidential proclamation?

This one is law-adjacent and gloriously real. In 1984, President Ronald Reagan signed Proclamation 5219, officially designating July as National Ice Cream Month and the third Sunday of July as National Ice Cream Day. The proclamation notes that ice cream is enjoyed by over 90 percent of the American people and calls on citizens to observe the occasion with “appropriate ceremonies and activities,” which is government language for “go get a sundae.” Congress pushed the idea, Reagan signed it, and America gained its most enforceable holiday. So if anyone gives you a hard time about that second scoop this month, you can tell them, accurately, that you are simply honoring a presidential proclamation.


Send this to the biggest ice cream fanatic you know… they’re going to bring up the oyster flavor at every cookout for the rest of the summer.
