Baked alaska, also known as bombe alaska, omelette norvégienne, omelette surprise, or omelette sibérienne depending on the country, is a dessert consisting of ice cream and cake topped with browned meringue. the dish is made of ice cream placed in a pie dish, lined with slices of sponge cake or christmas pudding, and topped with meringue. the entire dessert is then placed in an extremely hot oven for a brief time, long enough to firm and caramelize the meringue but not long enough to begin melting the ice cream.
