Chef Sol Han’s sour cream and onion dip is served in an actual onion.

First combined in 1954 by an enterprising home chef in the Golden State, sour cream and Lipton’s dehydrated onion soup mix came together to form a culinary creation that became known as California Dip thanks to its state of origin.

The dip was an instant hit and news of its creation “spread through Los Angeles faster than a canyon fire,” according to Jean Anderson, the author of The American Century Cookbook: The Most Popular Recipes of the 20th Century. “Newspapers printed the recipe, onion soup mix sales soared, and Lipton executives, a continent away in New Jersey, were ecstatic,” Anderson wrote in her 1997 book. “They tracked down the recipe, perfected it, and beginning in 1958, printed it on every box of Lipton Recipe Secrets Onion Soup Mix.”

Over the years, Califonia dip has clearly become better known as sour cream and onion dip and is mass-produced by all sorts of manufacturers as well as made in home kitchens using the same Lipton mix that started the culinary craze back in the ’50s. (Not to be confused with another dip-related fad that took place in the same decade.)

At Korean American restaurant LittleMad in New York City, a favorite of The New York Times that opened in 2021, the sour cream and onion dip is served inside a halved onion with deep-fried maitake mushrooms on the side for dunking purposes. The brainchild of chef Sol Han, the fried buhsut has quickly become as popular as the original dip that inspired it. “Instead of just giving you sour cream and onion dip, I wanted to utilize the onion as a vessel and provide the experience of using the whole thing,” Han tells InsideHook. “When you open it, there’s an element of surprise. Literally everyone smiles when we serve it. Everyone. It’s pretty simple, but it’s fun.”

LittleMad’s Fried Buhsut is an insane onion dip.
This next-level onion dip is the culinary creation of chef Sol Han.

A former cook at Manhattan restaurants like Le Coucou and Michelin-starred Ai Fiori who grew up helping out in the kitchen of his parents’ restaurant on Long Island, Han came up with the umami-filled dip as somewhat of a nod to a childhood favorite.

“Growing up, I just loved dip and chips. Ruffles chips with Ruffles sour cream and onion dip is really, really tasty. This is my gourmet version of it,” Han says. “The umami powder really elevates everything. It’s a game-changer we should be putting on everything. It brings next-level flavor. It’s almost like MSG without the MSG.”

Amped up by additional ingredients including caramelized onions and garlic confit, LittleMad’s fried buhsut is only available to customers who order the restaurant’s tasting menu — unless Han makes an exception. “I don’t recommend breaking rules, but they are meant to be broken,” he says. “If you’re sitting at the bar ordering cocktails and are like, ‘Ah, I just want the mushroom,’ maybe we could break some rules and sell it to you.”

Or you could just make it yourself.
