any of the videos with Jaques Pepin doing omelettes, There’s alot of things in those videos that will 100% up your omelette game. The country omellete is a favorite around here. (Also the classic scrambled, even if they’re too wet for me… certain people like them better that way.)
(by the way… Jacques fancied them up first… that’s the ‘Classic Omelette’… though that one must be newer because it wasn’t filmed with a potato)
