Why it works: Pecans and vanilla are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,691 recipes. Both carry alpha-pinene, which smells pine, turpentine. The science ↓
Wedding Cake.
Ingredients
Directions
The book says “a hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the cake
Cream the butter and sugar together until light and fluffy.
Add the egg yolks, water, and chopped pecans, mixing well.
Sift the baking powder with the flour and add it alternately with the beaten egg whites to the mixture.
Divide the batter into four layers and bake in a hot oven at 400°F (200°C) until golden.
Make the filling and finish
For the filling, combine ¾ cup butter, 1½ cups sugar, 4 egg yolks, and the juice of 4 lemons in a saucepan.
Beat the mixture over low heat until thickened.
Ice the cake with the cooked icing.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Creams with sugar to trap air, giving the cake a light, tender crumb.
- Eggs
- Yolks add richness and structure, while beaten whites lighten the batter for rise.
- Flour
- Forms the main structure of the cake as it sets in the oven.
- Baking powder
- Releases gas in the batter, helping the layers rise.
- Sugar
- Sweetens the cake and helps create a light, fluffy texture when creamed.
The step that matters
Beat the lemon filling over low heat until thickened. Egg yolks thicken by gentle heat but can scramble if the heat is too high. Low, steady heat with constant beating keeps the filling smooth.
Swap the pecans
How well each one fits the dish's main ingredients (butter, sugar, egg, vanilla, flour):
- Almondfits better
- Chestnutfits better
- Macadamia nutfits better
- Pecansthe original
Fit is the average pairing score against butter, sugar, egg, vanilla, flour. Candidates are from the same food group and used in at least 100 recipes.
