“Our mayonnaise is not a sauce, but a secret weapon,” said chef Igor Maslov of the Yankee Potroshok chain in an investigation by Afisha magazine.
It turns out the whole trick is in ordinary... carbonated water!
“We beat mayonnaise with mineral water (2 tablespoons per glass) – this makes it airy, like a soufflé,” the chain’s technologist revealed.

Chef Jamie Oliver confirmed on Quick & Easy Food:
"Soda contains CO₂, which creates microbubbles. Mayonnaise becomes lighter and does not interrupt the taste of dishes."
But that's just the beginning. Cook's Illustrated magazine conducted an experiment: two mayonnaises - regular and whipped with soda - were spread on sandwiches.
90% of tasters chose the second: “Melts in your mouth like a restaurant sauce.”
Chemist and technologist Olga Markova explained in the Science of Taste podcast:
"Carbon dioxide reduces the density of the emulsion. Mayonnaise is better absorbed into products - for example, into potatoes for salad."
The most unexpected review came from French chef Pierre Hermé , creator of Ladurée desserts:
"I add carbonated mayonnaise to the biscuit dough - it rises 20% higher. It's sacrilege, but the result is impeccable!"
User Denis from Novosibirsk wrote in the blog Rebel's Kitchen: "I mixed mayonnaise with tonic (instead of soda) - I got a sauce with a bitter aftertaste. Ideal for fish!"
But the main secret of "Yankee Giblet" was revealed by a former chef of the chain:
"We add a pinch of turmeric to the mayonnaise. It doesn't change the taste, but it gives it a golden hue - like homemade egg sauce."
Blogger Katya from the YouTube channel Sauces of the Day tested it: "Turmeric + soda + garlic - it's an analogue of Caesar sauce. Now I don't spend 200 rubles on store-bought!"
Scientists from the Food Hydrocolloids Journal have found a scientific basis: “CO₂ bubbles stabilize the emulsion – mayonnaise does not separate even after a month.”
Chef Jon Snow from Hell's Kitchen conducted an experiment: "I whipped up mayonnaise with soda and truffle oil - guests thought it was a $100 sauce." And user Olya from Moscow admitted in the Instagram account Lifehacks for the Lazy: "I make this mayonnaise once a week - my husband praises it as if it were the first time!"
