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
Make the sponge
Mix the yeast with the water thoroughly.
Stir in the flour to make a dough.
Knead the dough into a ball.
Cut a cross on the top of the dough.
Place the dough in a saucepan of lukewarm water.
Make the batter
Beat the remaining flour, salt, and butter with 2 eggs until smooth.
Add the other 2 eggs one at a time, beating well after each addition.
Incorporate the light ball of sponge into the mixture.
Beat the mixture until smooth.
Bake and soak
Turn the mixture into well-buttered molds.
When the dough has nearly doubled in size, bake for 20 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Forms the dough and gives the cakes their structure as it sets in the oven.
- Eggs
- Add structure, richness and lift to the batter as they set when baked.
- Yeast
- Ferments the dough so it rises and gives the cakes their light, airy crumb.
- Butter
- Adds fat for richness and a tender crumb, and greases the molds.
- Sugar
- Sweetens the cakes and, boiled with water, forms the syrup that soaks them.
- Rum
- Adds aroma and flavour to the syrup that soaks into the cakes.
The step that matters
Pour the syrup over the hot cakes. Hot cakes are porous and absorb the syrup evenly, while cooled cakes stay dry on the inside. The syrup should be thick but hot so it soaks in rather than pooling on top.
“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.
