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

Lard
Fat coats flour particles, keeping the crust tender and flaky when baked.
Flour
Forms the main structure that holds the crust together.
Egg white
Binds the dough and helps it set and hold its shape in the oven.
Sugar
Adds sweetness and helps the crust brown as it bakes.

The step that matters

Mix until combined. Stirring the dough too much develops gluten, which makes the crust tough instead of tender. Mix only until the dough holds together.
