Ingredients
1½ tbsp Butter
1½ tbsp All-purpose flour
1 cup Double-rich fish stock
½ cup Heavy cream
2 Hard-cooked eggs, peeled and chopped
2 tbsp Capers, rinsed and coarsely chopped
Salt
Freshly ground white pepper
Directions
In a saucepan over medium heat, melt the butter until it foams gently, about 1 minute.
Sprinkle the flour over the melted butter and whisk constantly for 2–3 minutes to cook out the raw flour taste and create a light golden roux. Do not brown.
Gradually pour in the fish stock while whisking continuously to prevent lumps from forming. Continue whisking until the mixture thickens and comes to a gentle simmer, about 3–4 minutes.
Reduce heat to low and stir in the heavy cream until fully incorporated and the sauce is smooth and homogeneous.
Gently fold in the chopped hard-cooked eggs and rinsed capers, stirring just until combined.
Season to taste with salt and freshly ground white pepper. Remove from heat and serve warm.
Comments
This is a rare sauce that checks every box for a Charlotte cook. All eight ingredients are pantry staples or common finds at Harris Teeter, Food Lion, or Kroger, with nothing requiring a special trip; fish stock is the only item that demands a moment's thought, but it's available frozen or in aseptic cartons at any major grocer here. The cost per serving lands under $2 when you account for bulk butter and eggs, making it genuinely economical. The stated 25 minutes is honest—whisking a beurre blanc derivative and tempering eggs is straightforward, not fussy. The sauce is built for weeknight service over fish, chicken, or vegetables, reheats gently over low heat without breaking, and feeds four without drama or constant attention.
