I have one sourced drink connected to Belgium. The label on each card says how: where it began, what the country is known for, what people drink there, or where the origin is disputed.

Duikboot
Flanders
IconicRegional drink
A small glass of jenever dipped into a glass of lager. Wikipedia places it in Flanders and the south of the Netherlands, and the kopstoot is the version where the jenever glass stays beside the beer.
Wikipedia places the duikboot in Flanders and the south of Holland. Jenever has a 13th-century Flemish text describing juniper added to a distilled spirit and an Antwerp doctor's recipe from 1522. The sources give no date for the duikboot itself.
