Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Coulibiac
Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the dough
Dissolve the yeast in warm milk in a basin.
Strain into another basin and mix in enough flour to make a soft paste.
Cover with a cloth and let it rise in a warm place.
Once risen, gradually add 4 cups of sifted flour, melted butter, eggs, and a little milk.
Work the paste until it has some consistency and let it rise again.
Assemble and bake
Roll out half of the Coulibiac paste into a square about ½ inch thick and place it on a well buttered baking sheet.
Layer with boiled rice, chopped hard-boiled eggs, and eel pieces.
Sprinkle with ground spice, chopped herbs, salt, and pepper.
Cover with the remaining half of the paste, sealing the edges.
Shape it into a ball and bake in a moderate oven at 350°F (175°C) until done.
Serve hot on a dish.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Yeast
- Produces gas that makes the dough rise and become light.
- Eggs
- Add structure and richness, helping the filling and paste set when baked.
- Butter
- Adds fat that tenderises the dough and gives a rich flavour and browning.
- All-purpose flour
- Forms the gluten network that gives the paste its structure and chew.
- Eel
- Provides the main savoury filling and rich flavour.
The step that matters
Letting the dough rise. Yeast needs warmth and time to produce gas; a under-risen paste stays dense and heavy, while proper rising gives a light, airy crust.
