This recipe is for one omelette. Double, triple, or quadruple it, but keep the same proportions. Big omelettes are hard to handle.
Put eggs, sugar, crème, Grand Marnier, and salt into bowl ready to beat. (Add salt now; it’s not possible to salt a dessert omelette after it is cooked.)
Toast butter in scoured omelette pan, but do not let it burn. Beat
