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
Prepare
Preheat the oven to 400°F (200°C).
In a large bowl, cream together the butter, lard, and sugar until smooth.
Gradually add the flour and mix until a dough forms.
Roll out the dough to about ½ inch thick on a floured surface.
Cut into desired shapes, such as fingers or triangles.
Bake and serve
Place on a baking sheet lined with parchment paper.
Dust with sugar if desired.
Return to the oven for 1 more minute to fix the sugar.
Bake until lightly colored, being careful not to burn.

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
- All-purpose flour
- Forms the dough's structure, setting the shape of the cookies as they bake.
- Unsalted butter
- Adds richness and a tender, crumbly texture through its fat content.
- Lard
- Adds fat that keeps the shortbread tender and short in texture.
- Sugar
- Adds sweetness and helps the surface brown during baking.
The step that matters
Bake until lightly colored, being careful not to burn.. Sugar browns quickly at high oven heat, and thin shaped pieces can go from pale to burnt within minutes. Checking early keeps the flavor clean and the color even.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
