Why it works: Flour and butter are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare
Preheat the oven to 350°F (175°C).
Make the filling
In a bowl, combine sugar, melted butter, eggs, and flour.
Beat the mixture well until smooth.
Pour the mixture into a prepared pastry crust.
Bake
Bake until set and golden.

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 custard as they coagulate with heat, giving structure.
- Flour
- Thickens the filling and gives it body so it holds its shape when sliced.
- Melted butter
- Adds richness and moisture, and helps the filling turn smooth and tender.
- Sugar
- Adds sweetness and helps the top brown as it bakes.
The step that matters
Bake until set and golden. Egg proteins set with heat, so the filling is done when it is firm at the edges and barely wobbles in the centre. Overbaking makes eggs tighten and weep, leaving the filling grainy and watery.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
