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 ↓
Orange Loaf Cake
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. The book gives no cooking times either; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.
Make the batter
Preheat your oven to 350°F (175°C).
Beat the butter and sugar until light and creamy.
Add the beaten egg yolks, orange juice, grated rind, and cold water; mix well.
Sift together the flour and baking powder, then add to the mixture, beating well.
Fold in the stiffly beaten egg whites.
Pour the batter into a greased loaf pan and bake for about 50-60 minutes or until a toothpick comes out clean.
Make and spread the frosting
For the frosting, beat the egg white until stiff, then gradually add the sugar.
Stir in the orange juice and grated rind, mix well, and spread over the cooled cake.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Whole eggs and whipped whites give the cake its structure and light, airy crumb.
- Butter
- Adds fat for a tender texture and rich flavour.
- Sugar
- Sweetens the cake and helps it brown while creaming with butter traps air for lightness.
- Flour
- Forms the cake's main structure as its proteins set during baking.
- Baking powder
- Releases gas in the batter, helping the cake rise.
- Orange rind
- Adds aromatic citrus flavour throughout the cake and frosting.
The step that matters
Folding in the stiffly beaten egg whites. Whipped whites hold the air that lightens the batter. Stirring them vigorously deflates that foam, leaving a dense cake, so fold gently until just combined.
