mustard soup

Groningen Mustard Soup is a creamy northern Dutch soup defined by the region's mustard. This profile follows Visit Groningen's plain five-ingredient base and does not turn its optional bacon, leek, salmon, prawn, sausage, bread or cheese garnishes into required ingredients.

Groningen mustard supplies pungent, tangy heat against the mellow dairy richness of butter and cream. Vegetable stock adds savoury depth, while the flour roux softens the mustard's edge and gives the soup body.

The soup is smooth, pale cream to muted yellow, often finely speckled by mustard. Its consistency is velvety and lightly thickened, remaining pourable rather than setting like a sauce.
