Why it works: Butter and potato are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 6,456 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Tartlets, Balmoral
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.
Prepare
Make the short crust paste and line 12 patty pans.
Cream the butter and sugar until thick and white.
Make the filling
Stir in the yolk of the egg, then add the cake crumbs, cherries, peel, and cornflour.
Whisk the egg white until stiff, then gently fold it into the mixture.
Fill the patty cases with the preparation.
Top and bake
Place 2 narrow strips of paste on top of each tartlet.
Bake for about 20 minutes at 350°F (175°C).

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- The yolk binds the filling and the whisked white lightens it so the tartlets stay tender.
- Butter
- Creamed with sugar, it traps air and gives the filling a rich, tender texture.
- Castor sugar
- Creamed with butter, it helps create a light, thick base and adds sweetness.
- Cake crumbs
- Add body and softness to the filling, absorbing moisture as it bakes.
- Cornflour or potato flour
- Thickens the filling so it sets softly rather than running when baked.
The step that matters
Folding in the stiff egg white. Whisked egg white holds air that lightens the mixture. Folding gently keeps that air in, so the filling rises and bakes tender rather than dense and flat.
Swap the potato
How well each one fits the dish's main ingredients (butter, sugar, egg):
- Sweet potatofits better
- Asparagusfits better
- Leekfits about as well
- Potatothe original
Fit is the average pairing score against butter, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
