Why it works: Butter and milk 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 ↓

Ingredients
Directions
The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
In a bowl, break the eggs and add sugar and melted butter. Stir until light and smooth.
Add lemon juice, biscuit powder, and milk as needed to achieve a smooth mixture.
Bake
Line tartlet pans with puff pastry and fill with the mixture.
Bake in a 400°F (200°C) oven until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the filling into a firm, sliceable custard as they bake.
- Butter
- Adds richness and a smooth, tender texture to the filling.
- Sugar
- Sweetens the filling and helps it blend smoothly with the eggs and butter.
- Lemon juice
- Adds acidity that brightens the flavor and balances the sweetness.
- Finger biscuits
- Add dry crumb body and a light biscuity flavor to the filling.
The step that matters
Bake until set. Eggs firm up as their proteins coagulate with heat. Pulling the tarts too early leaves a runny filling, while overbaking can make the custard grainy and rubbery.
