Flambéing is about more than putting on a show. Although, if you can pull it off, you look pretty, darn cool doing it. In truth, those big flames equal big flavour. The liquor imbibes the dish with it's own rich flavour profile, while the heat burns off the booze. It also simultaneously deglazes your pan, incorporating all that caramelized deliciousness back into the dessert. But remember, safety first: Don't add too much alcohol and step back before igniting the liquid.
