|Place of origin||Netherlands|
|Main ingredients||pilk, vla (or eggs, cornstarch, vanilla, sugar)|
The word vla was first documented in the 13th century and originally referred to any custard-like substance covering cakes or other baked goods. The word vlaai is related and has since come to refer a type of pie.
Traditionally vla is made with eggs, sugar and fresh milk, although some industrial producers use cornstarch rather than eggs today. Vla is available in many different flavors, of which vanilla is most popular. Other flavors include chocolate, caramel, banana, orange and apple.
Vla was originally sold in glass bottles and the consistency made extracting the complete amount difficult, so a special bottle scraper (flessenschraper or flessenlikker) was specifically designed. Despite the fact that vla is now normally sold in cartons, these scrapers are still common in Dutch family kitchens.
