Why it works: Flour and egg are a kitchen classic. They rank in the top 15% of all ingredient pairs, and cooks put them together in 106,462 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Pie Crust
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.
Make the dough
Sift together the flour and salt.
Add the oil and work it in thoroughly.
Gradually pour in the cold water and knead into a firm dough with minimal handling.
Shape and bake
Roll out the dough on a floured surface to a thin sheet.
Lay the rolled dough in pie plates.
Before adding the filling, brush the crust with beaten egg white to prevent sogginess.
Bake in a moderate oven at 350°F (175°C) until both the upper and lower crusts are browned.

Flour and egg barely smell alike, yet cooks put them together in 106,462 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the structure of the crust as gluten develops when kneaded with water.
- Oil
- Coats flour particles to tenderize the crust and add richness.
- Cold water
- Hydrates the flour to bind the dough while keeping it firm.
- Egg white
- Forms a thin barrier that helps keep the crust from going soggy under the filling.
The step that matters
Minimal handling of the dough. Overworking cold-water dough develops too much gluten, making the crust tough rather than tender. Mixing only until it holds together keeps the crust flaky and short.
Swap the coconut
How well each one fits the dish's main ingredients (flour, egg):

- Coconutthe original
Fit is the average pairing score against flour, egg. Candidates are from the same food group and used in at least 100 recipes.
