Why it works: Sugar and cinnamon are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 30,779 recipes. Both carry guaiacol, which smells smoky, sweet. The science ↓

Ingredients
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
Preheat your oven to 350°F (175°C).
Make the mixture
Beat the loaf sugar with the egg whites until well combined.
Add the oil of cinnamon, lemon juice, or orange‑flower water for flavor.
Bake and serve
Bake in the same way as meringues until set.
Serve in a napkin or use to garnish dishes of preserves.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Loaf sugar
- Forms the bulk of the mixture and gives the sweet, crisp structure once baked.
- Egg whites
- Whisked with sugar to create the foam that sets into a light, crisp shape.
The step that matters
Bake in the same way as meringues until set. Sugar and egg white mixtures dry and set slowly at low heat; baking too hot can brown them before the interior firms, so check for a set, dry surface rather than colour.
