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 ↓
Pattie Shells
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the dough
Preheat the oven to 350°F (175°C).
In a bowl, mix the flour, butter, lard, and water until combined.
Shape and bake
Roll out the dough and shape it into patty shells.
Place the shells on a baking sheet and bake until golden.

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.

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 gluten network that gives the shells their structure.
- Butter
- Creates flaky layers as its water turns to steam in the oven.
- Lard
- Adds tenderness and flakiness by coating flour particles and limiting gluten.
The step that matters
Bake until golden. Browning comes from Maillard reactions and caramelization on the surface, which signal that the shells are dried and set. Pulling them early can leave the centers doughy and pale, while baking too long can make them dry and brittle.
