Joppiesaus is a condiment from the Netherlands based on mayonnaise with mild curry spices. It is commonly offered in fast food restaurants in the Netherlands and Belgium, but is also available in grocery stores.
Joppiesaus was created by Janine "Joppie" de Jager of Annie's Snackbar in Glanerbrug, a village in the Netherlands on the border with Germany. It consists of mayonnaise with a 'secret blend' of spices. In 2002 the sauce entered industrial production by Elite Salades & Snacks, a company in Neede,[1] who legally own the sauce's name.[2][3]
Joppiesaus is a vegetable oil-based mayonnaise with onion and curry powder spices.[4][5] The flavour is akin to that of a mild curry mayonnaise and the colour is a vivid turmeric yellow. The sauce is commonly served with french fries and other deep-fried or fast food dishes.
