Which liqueur is named on Wikipedia as a usual choice for crêpe Suzette?

Grand Marnier is the liqueur named on Wikipedia as a usual choice for crêpe Suzette.

Crêpe Suzette is a French dessert made with crêpes and a citrus-flavoured butter sauce. The sauce traditionally includes sugar, butter, orange or tangerine juice, and grated zest. Grand Marnier adds both sweetness and orange aroma, and the dessert is often flambéed during presentation, creating its famous tableside flames.

Grand Marnier is an orange-flavoured French liqueur made from Cognac, bitter-orange essence, and sugar. Alexandre Marnier-Lapostolle created the original product in 1880. Its Cognac base gives it a deeper, brandy-like character than many orange liqueurs made from neutral spirits.

The history of crêpe Suzette is disputed. One story credits Henri Charpentier with accidentally igniting a sauce in Monte Carlo in 1895; other accounts connect the dish with chef Auguste Escoffier or actress Suzanne Reichenberg. The origin remains debated, but Grand Marnier’s association with the dessert is firmly established. Other orange liqueurs can be used, yet Grand Marnier is the canonical answer here.
