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 ↓
Sand Tarts
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.
Make the dough
Cream the butter in a bowl.
Add the sugar, flour, and eggs; mix to form a stiff paste.
Roll the dough very thin and cut into desired shapes.
Decorate and bake
Brush the tarts with the beaten egg white.
Sprinkle powdered sugar and cinnamon over the tarts.
Top with a few blanched almonds.
Bake at 350°F (175°C) until golden.

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
- Provides the structure that holds the stiff dough together as it bakes.
- Granulated sugar
- Adds sweetness and helps the tarts brown and crisp in the oven.
- Unsalted butter
- Adds fat that makes the dough rich and tender.
- Eggs
- Bind the dough and, through the white, give the tops a glossy surface.
The step that matters
Roll the dough very thin. Thin dough dries and crisps as it bakes, while thick dough stays soft and cakey in the center. Even thickness also ensures the tarts bake at the same rate, so none burn while others remain pale.
“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.
