Why it works: Cream and sugar are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Moonshine Cake
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Sift the flour, cornstarch, and cream of tartar together twice.
Make a syrup by boiling water and sugar together.
Make the batter
Once the syrup is cool, pour it into well-beaten egg whites.
Stir in the well-beaten yolks and the sifted flour mixture.
Pour the batter into a deep ungreased pan with a tube.
Bake and cool
Bake in a slow oven at 300°F (150°C) for 40 to 60 minutes.
Do not open the oven door for the first 20 minutes.
When done, turn the cake upside down on glasses until it cools and sweats.
Frost as desired.

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 main structure once its starch sets during baking.
- Eggs
- Whites trap air for lift, while yolks add richness and help bind the crumb.
- Baking powder
- Releases gas in the batter to help the cake rise.
- Cream of tartar
- Stabilises the beaten egg whites so their foam holds during mixing and baking.
- Cornstarch
- Softens the crumb by diluting the flour's gluten-forming proteins.
- Sugar
- Sweetens the cake and helps keep the crumb moist and tender.
The step that matters
Do not open the oven door for the first 20 minutes. The batter's egg-white foam is still setting early in baking. Opening the door drops the oven temperature and can make the rising cake sink or collapse.
“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.
