Why it works: Cinnamon and vanilla match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 5,287 recipes. Both carry 4-methoxybenzaldehyde, which smells sweet, anise. The science ↓
Chocolate Frappe
Ingredients
Directions
Make the chocolate syrup
Combine sugar, grated chocolate, and 1 cup of boiling water in a saucepan.
Cook until it forms a shiny paste, stirring constantly to prevent burning.

Stir in cinnamon and vanilla.
Assemble and serve
Add 1 cup of cream and beat until light.
Pour into tall glasses filled with cracked ice.
Top with a spoonful of whipped cream.

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 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
- Granulated sugar
- Dissolves into the boiling water to form the syrup and adds sweetness.
- Grated chocolate
- Provides the chocolate flavor and, when cooked, thickens into a shiny paste.
- Cream
- Adds richness and, when beaten, a light, airy texture.
The step that matters
Cooking the syrup down to a thick consistency. Stirring constantly keeps the sugar and chocolate from scorching on the bottom of the pan. Boiling the mixture down concentrates the sugar, which gives the syrup its thick body and keeps the frappe from tasting watery once the ice is added.
