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
Make the dough
Place the flour on a clean surface and form a hollow in the center.
Add the salt and dissolved butter to the hollow.
Pour in the hot water and mix everything together with your hands until a firm paste forms.
Knead the paste compactly with both hands.
Rest
Wrap the paste in a cloth and place it in a warm stewpan until ready to use.

Shared aroma: isobutyraldehyde (malty, green).
Flour and butter barely smell alike, yet cooks put them together in 124,287 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 paste, giving it body and holding its shape.
- Hot water
- Partly gelatinizes the flour's starch, making the paste pliable and easier to shape.
- Butter
- Adds fat that tenderizes the paste and keeps it from drying out.
The step that matters
Pouring in the hot water and mixing until firm. Hot water must be added to the flour and mixed thoroughly so the starch partly gelatinizes. This gives a pliable, cohesive paste; uneven mixing leaves dry pockets and weak spots that crack when shaped.
