Why it works: Potato and chicken are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 2,756 recipes. Both carry (z)-4-decenal, which smells green, must. The science ↓
Potato Casserole
Ingredients
Directions
The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the potato base
In a pot, combine mashed potatoes, egg yolks, cream, and butter. Stir over low heat until hot.
Beat the mixture until very light, then season with salt and pepper.
Form the mixture into a neat border on a baking sheet or platter.
Bake and serve
Brush the border with beaten egg and bake in a 400°F (200°C) oven until golden brown.
Fill the center with fricassee of chicken, rabbit, or veal, and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mashed potatoes
- Form the bulk of the casserole and give it a soft, tender body.
- Egg yolks
- Add richness and help bind the mixture so it holds its shape.
- Cream
- Adds moisture and richness, keeping the potato mixture smooth and soft.
- Butter
- Adds fat for flavor and a silky texture in the potato mixture.
- Beaten egg
- Brushed on the border to promote even golden browning in the oven.
The step that matters
Beating the potato mixture until very light. Beating incorporates air and makes the mixture light and smooth, so the border piped or shaped holds its form and bakes up tender rather than dense or gluey.
Swap the potato
How well each one fits the dish's main ingredients (egg, butter, cream, pepper, chicken):
- Potatothe original
- Capsicumfits about as well
- Asparagusfits about as well
- Spinachfits less well
Fit is the average pairing score against egg, butter, cream, pepper, chicken. Candidates are from the same food group and used in at least 100 recipes.
