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 ↓
Baba or Rum Cakes
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 sponge
Mix the yeast into the water thoroughly.
Stir in flour to make a dough and knead into a ball.
Cut a cross on top of the dough and set it 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 and beat until smooth.
Turn the mixture into well-buttered molds.
Bake and soak
Let rise until nearly double in bulk, then bake for 20 minutes at 350°F (175°C).
Boil the sugar and water until it forms a thick syrup.
Remove from heat and add the rum.
Pour the hot syrup over the hot cakes.
Serve warm or cold.

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
- Flour
- Forms the dough and the structure that holds the cakes as they rise and bake.
- Eggs
- Provide structure and richness, setting the crumb as the cakes bake.
- Butter
- Adds fat and richness, giving the cakes a tender texture and flavor.
- Compressed yeast
- Produces gas that makes the dough rise, giving the cakes their light, airy crumb.
- Sugar
- Forms the thick syrup that sweetens the cakes and keeps them moist.
- Rum
- Adds aroma and flavor to the syrup soaking into the cakes.
The step that matters
Let rise until nearly double in bulk. Yeast needs enough time to produce gas and expand the dough; underproofed cakes stay dense, while overproofed ones may collapse in the oven.
