Why it works: Butter and flour 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 ↓
Fig Layer Cake
Ingredients
Directions
Make the fig filling
Combine ½ cup sugar and 1 cup water in a saucepan. Stir until the sugar dissolves.
Add 1 pound chopped figs. Stew until soft and smooth.
Cool the fig mixture.
Make the cake batter
Cream ½ cup butter in a bowl. Gradually add 1½ cups sugar, beating until light and creamy.
Add 1 cup water and 2½ cups sifted flour little by little, beating until smooth.
Stir in 2 teaspoons baking powder.
Beat the whites of 4 eggs to stiff peaks. Gently fold the beaten egg whites into the batter along with 1 teaspoon flavoring extract.
Bake the batter in three layers.
Assemble and ice
Spread the cooled fig mixture between the layers.
Soak 1 tablespoon gelatin in 1 tablespoon cold water for 10 minutes. Add 2 tablespoons boiling water and stir until gelatin dissolves.
Mix in enough powdered sugar to achieve a spreadable consistency. Flavor the icing.
Spread the icing on the cake.
Let the cake stand in a cool place to dry.

Butter and flour 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
- Eggs
- Whipped whites trap air, giving the layers lift and a light, airy crumb.
- Butter
- Creamed with sugar, it adds richness and a tender texture to the cake.
- Flour
- Provides the structure that holds the layers together around the filling.
- Figs
- Cooked into a soft, sweet filling that adds moisture and fruit flavor.
- Baking powder
- Releases gas in the batter, helping the layers rise.
- Gelatin
- Sets the icing so it spreads and holds its shape on the cake.
The step that matters
Folding in the egg whites. Beaten whites hold the air that lifts the layers. Stirring them in vigorously knocks out that air, so the cake bakes flat and dense. Fold gently, just until no white streaks remain.
Swap the fig
How well each one fits the dish's main ingredients (sugar, butter, flour, egg):
- Raisinfits better
- Vanillafits better
- Figthe original
- Lemonfits about as well
Fit is the average pairing score against sugar, butter, flour, egg. Candidates are from the same food group and used in at least 100 recipes.
