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 ↓
Snow-cake
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the batter
Beat the butter until creamy.
Add the beaten egg and mix well.
Incorporate the flour, sugar, and lemon juice; mix until combined.
Add another egg, then beat for 30 minutes until the mixture turns white and light.
Bake
Line a flat baking pan with buttered parchment paper.
Pour the batter into the pan.
Place the pan in a 300°F (150°C) oven.
Bake for 1 to 1.5 hours without allowing it to brown.
Cool and serve
Let the cake cool for a few minutes.
Cut the cake into small squares.
Transfer the pieces to a large flat dish.
Cool the pieces completely before storing.

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 starch and gluten network that gives the cake its structure.
- Unsalted butter
- Adds fat for a tender crumb and rich flavour.
- Powdered sugar
- Sweetens the cake and yields a fine, tender crumb.
- Egg
- Binds the batter and, when beaten, traps air that lightens the texture.
- Lemon juice
- Adds acidity and bright aroma that balance the sweetness.
The step that matters
Beating the batter for 30 minutes. Long beating traps air in the fat and egg, which makes the cake light and pale. Stopping early leaves a denser, heavier cake.
