It’s fucking gross.
The smell, the taste, the sound it makes when people scoop big globs of it. And fuck “chefs” who try to church it up and call it aioli to put it on everything.
Your “secret sauce” isn’t a fucking secret it’s fucking mayo and go fuck yourself I don’t want it.
Even real mayonnaise comes across as super eggy though.
Eggy flavor comes from the yolk. If you don’t want that, you can use eggs whites as your emulsifier. So long as your measurements by weight or volume are the same, whites work just as well as whole eggs.
