Why it works: Vanilla and sugar are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 35,032 recipes. Both carry beta-damascenone, which smells apple, rose. The science ↓
Small Royal Cakes, with Vanilla
30 cakesIngredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the vanilla sugar
Chop the vanilla stick finely and pound it with the sugar, then pass the mixture through a silken sieve.
In a small bowl, mix the vanilla sugar with the egg white using a silver spoon until soft.
Shape and top the cakes
Roll out the puff pastry to 1/6 inch thick.
Cut out 30 oval cakes using a 2.5-inch by 1.5-inch cutter, ensuring the ends are pointed.
Cover each cake with 1/4 teaspoon of the vanilla icing, spreading it evenly.
Let the cakes sit for 30 minutes to prevent the icing from cracking.
Bake
Bake the cakes in a moderate oven at 350°F (175°C).
Press down any risen icing after removing from the oven.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Vanilla
- Provides the main aroma and flavour of the icing.
- Sugar
- Sweetens the icing and helps form a smooth, spreadable paste with the vanilla.
- Egg white
- Binds the vanilla sugar into a soft icing that holds its shape on the pastry.
- Puff pastry
- Forms the flaky, layered base of each cake as it rises in the oven.
The step that matters
Pressing down risen icing after baking. The egg white icing puffs as it heats, and it can crack or lift off the pastry. Pressing it down while still warm helps it settle flat on the cake.
“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.
