Syllabub is an old English sweet cream dessert, whipped and curdled with spirits, citrus, or both. The Lee Bros. Charleston Kitchen provides a recipe for a chilled cream cloud flavored with sherry and lemon.

On the list of great culinary innovations that Britain has given the world, desserts would be at the top. Although trifle and pudding are the most well-known, the humble syllabub is my personal favorite. What comes down to a flavored whipped cream is made more complex by the slight curdle the cream gets from citrus, and the sweet alcohol burn given to the cream by sugar and brandy.
