Joppiesaus is a Dutch curry-onion mayonnaise served with fries, kroket, and frikandel. The original recipe is a trade secret, but the home version combines mayonnaise with curry powder, finely minced onion, mustard, and a touch of vinegar and sugar. Resting the sauce lets the onion soften and the curry flavor meld into the mayo.

Makes ca. 250 ml, about 4 servings

Ingredients

200 g mayonnaise
1 small onion (70 g), very finely minced
2 tsp curry powder (mild yellow)
1 tsp white wine vinegar
1 tsp sugar
1 tsp Dijon mustard
1/4 tsp black pepper, freshly ground
1 pinch salt
Optional: 1 tbsp ketchup (adds color, slight tang)
Optional: pinch of cayenne pepper (for heat)

Directions

Mince the onion as finely as possible - the pieces should nearly dissolve into the sauce. A microplane or food processor pulse works well.
Combine the mayonnaise, curry powder, mustard, vinegar, and sugar in a bowl. Stir until the curry is evenly distributed and the sauce turns uniformly yellow.
Fold in the minced onion. Season with black pepper, salt, and cayenne if using. Add ketchup if you want a slightly deeper color and tanginess.
Cover and refrigerate for at least 30 minutes (1 hour is better) - this lets the onion soften and the curry flavor meld into the mayo.
Taste and adjust seasoning. Serve cold with fries, kroket, frikandel, or on burgers.

Notes

Onion size matters. The onion must be minced extremely fine. Visible chunks of onion are not the goal - the onion flavor should blend into the sauce.
Curry powder choice. A standard mild yellow curry powder (with turmeric, coriander, cumin, fenugreek) is the baseline. Madras curry or hot curry will shift the flavor significantly.
Blooming the curry. For deeper flavor, briefly fry the curry powder in 1 tablespoon of neutral oil over low heat for 1-2 minutes until fragrant. Cool completely before mixing into the mayo. This is optional but recommended.
Ketchup is optional. It is not in the commercial recipe’s spirit but appears in many home versions. It adds convenience (sweetness + acidity + color in one ingredient) but is not essential if you have vinegar and sugar.
Storage. Keeps 3-4 days refrigerated in a sealed container.
