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
Make the dough
In a bowl, mix flour and baking powder.
Cut in shortening until mixture resembles coarse crumbs.
Add ice water gradually, mixing until dough forms.
Roll and chill
Roll out the dough on a cold board, handling it as little as possible.
Cover the rolled dough with a cloth and chill in a cold place for 30-60 minutes.
Finish and bake
Brush the dough with egg white before baking for a flaky texture.
If using currants, wash, dry, and dredge them with flour before adding to the pie.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

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
- All-purpose flour
- Forms the main structure of the dough as its proteins bind with water.
- Shortening
- Coats flour particles to keep the crust tender and create flaky layers.
- Ice water
- Hydrates the flour while keeping the fat cold so the dough stays workable.
- Magic baking powder
- Releases gas for light rising in the crust.
- Egg white
- Brushed on the dough, it adds a glossy surface and helps browning.
The step that matters
Handling the dough as little as possible. Overworking develops gluten, making the crust tough, and warm handling melts the shortening, so the layers that make it flaky are lost.
Swap the currant
How well each one fits the dish's main ingredients (flour, egg):
- Raisinfits better
- Vanillafits better
- Lemonfits better
- Currantthe original
Fit is the average pairing score against flour, egg. Candidates are from the same food group and used in at least 100 recipes.
