Ingredients

Directions

The book says “a warm oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Make the filling

  1. Stew the mushrooms in a little water until done.

  2. Add butter, salt, and pepper to the mushrooms and mix well.

  3. Wet the flour with cream and mix it with the beaten egg yolks.

  4. Combine the mixture with the mushrooms and mix well.

Prepare and bake the rolls

  1. Cut the tops off the French rolls and scoop out the insides.

  2. Brush the insides with melted butter.

  3. Brown them in a 400°F (200°C) oven.

  4. Fill the rolls with the mushroom mixture.

  5. Replace the tops.

  6. Serve.

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

What each ingredient does

Mushrooms
Provide the main filling bulk and earthy flavor once stewed until tender.
Egg yolks
Bind the filling and set it into a soft, custard-like texture when heated.
Butter
Adds richness and moisture to the filling and browns the roll interiors.
Cream
Adds moisture and richness, creating a smooth, creamy filling.
Flour
Thickens the cream and egg mixture so the filling holds together.

The step that matters

Combine the flour, cream and egg yolks smoothly. Flour must be wetted with cream before adding it to the eggs so it does not form lumps. Lumps stay in the filling and give an uneven texture. Egg yolks thicken when heated, so the filling should be well mixed before it goes into the rolls.
