Why it works: Sugar and syrup match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 5,842 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Cafe Frappe
Ingredients
Directions
Make the coffee base
Brew strong coffee using a drip coffee pot and let it cool.
Mix the cooled coffee with 4 cups of heavy cream and sweeten with sugar syrup.
Stir in 1 tablespoon of vanilla extract.
Fold in 1 cup of whipped cream gently.
Serve
Place a large lump of ice in a punch bowl, pour in the mixture, and serve in glasses.
Optionally, freeze the mixture to a mush and serve in tall glasses.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Heavy cream
- Adds richness and a smooth, creamy body to the coffee.
- Sugar syrup
- Sweetens the coffee and balances its bitterness.
- Whipped cream
- Adds airy lightness and a softer texture to the drink.
- Strong brewed coffee
- Provides the main coffee flavour and aroma.
The step that matters
Fold in the whipped cream gently. Folding keeps the air trapped in the whipped cream. Stirring hard would deflate it and make the drink flat and dense.
