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 ↓
Squash Pie
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.
Prepare the filling
Strain the cooked squash through a sieve.
In a saucepan, boil the milk with the salt and butter.
Mix the strained squash, sugar, and lemon extract.
Gradually pour the boiling milk into the squash mixture, stirring constantly.
Add the beaten eggs (yolks and whites) last and mix well.
Bake
Prepare the pie pastry in the pie tins and pour the filling in.
Bake immediately in a preheated oven at 400°F (200°C) until set.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Cooked squash
- Forms the body and bulk of the custard filling, giving it its flavour and texture.
- Eggs
- Set the custard as they cook, giving the filling its structure.
- Milk
- Provides the liquid base that gives the filling its creamy, smooth texture.
- Sugar
- Adds sweetness and helps soften the set texture of the custard.
The step that matters
Adding the boiling milk to the squash. Pouring the hot milk in gradually while stirring constantly keeps the eggs from scrambling later. Adding the eggs last and mixing well spreads them evenly so the filling sets smoothly rather than in lumps.
Swap the lemon
