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 ↓
Pie Paste of Lard and Butter
Ingredients
Directions
Make the dough
Rub the lard into the flour until well combined.
Add just enough cold water to bind the mixture together.
Laminate
Roll out the dough thinly and spread butter over the surface.
Fold the dough twice, then roll it out again, dusting with flour.
Spread more butter on the surface and fold again.
Repeat this process a third time, using a total of ¼ pound of butter.

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.

What each ingredient does
- Lard
- Creates flaky layers by staying solid in the dough and separating strands of flour.
- All-purpose flour
- Forms the gluten network that gives the dough its structure.
- Butter
- Spread between folded layers, it adds richness and flavor and helps create separate flaky layers.
The step that matters
Keeping the fat cold during folding. If the lard and butter soften, they blend into the dough instead of staying as distinct layers, so the pastry loses flakiness. Keeping the dough cool between folds preserves the layers that steam apart during baking.
