Ingredients

Directions

Prepare the rolls

  1. Cut a round from the bottom of each roll, about half an inch from the edge, and set aside.

  2. Carefully scrape out the crumb from the rolls without breaking the crust.

Make the sauce

  1. In a saucepan, stir the flour over medium heat with the milk until thickened.

  2. Add the butter, stirring rapidly to prevent lumps, then season with pepper, salt, nutmeg, and parsley.

Fill and serve

  1. Once the sauce is cold, mix it with the minced meat and fill the rolls, replacing the round on top.

  2. Arrange the filled rolls on a serving dish for supper, luncheon, or high tea.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

All-purpose flour
Thickens the milk into a smooth white sauce that holds the filling together.
Butter
Adds richness and a smooth, silky texture to the sauce.
Milk, cream, or good white broth
Forms the liquid base of the sauce, giving it moisture and body.
Cooked veal or ham
Provides savoury meaty flavour and bulk to the filling.
Cooked chicken and tongue
Adds more savoury meat flavour and texture to the filling.
Oysters or lobster
Contributes a distinct briny, seafood flavour to the filling.

The step that matters

Adding the butter to the sauce. Flour thickened with milk forms lumps if it is not kept moving, and butter stirred in rapidly helps keep the sauce smooth. Lumps in a sauce cannot be fully removed once it has set, so constant stirring matters.

Swap the nutmeg

How well each one fits the dish's main ingredients (veal, chicken, oyster, flour, milk, butter, pepper):

  1. Parsleyfits about as well
  2. Nutmegthe original
  3. Thymefits about as well
  4. Marjoramfits about as well

Fit is the average pairing score against veal, chicken, oyster, flour, milk, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
