Quick mustard sauce for fish or egg

Ingredients for 1 servings:

• 125 g butter
• 100 g mustard
• 1 egg yolk
• 125 g natural yogurt
• e.g. salt and pepper
• n. B. sugar
• n. B. herbs

Instructions

Working time approx. 5 minutes; Cooking/baking time approx. 5 minutes; Total time approx. 10 minutes

without roux

Slowly melt the butter in a small saucepan on the stove over low heat. Meanwhile, place the mustard and egg yolk in a bowl and heat gently over a pan of simmering water; not too hot, so the egg doesn’t curdle! Now add the melted butter while stirring. Finally, stir in the yogurt and heat everything up again (do not boil!). If you like, you can add salt, pepper, sugar, or other herbs and spices to taste. The flavor varies depending on the mustard you use (basically any mustard will do, from medium to hot, even sweet mustard), so you might not need any additional seasoning. Personally, I prefer a simple, medium-hot mustard. The sauce goes well with fried fish or boiled eggs and potatoes.
