Why it works: Vanilla and chocolate are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 10,020 recipes. Both carry sotolon, which smells curry, maple. The science ↓
Chocolate Glace
Ingredients
Directions
Make the syrup
Combine sugar and water in a granite or earthenware saucepan.
Boil gently for about 5 minutes until bubbles form at the bottom.
Remove from heat immediately.
Do not stir or shake the sugar while cooking.
Make the icing
Pour the hot syrup in a thin stream into the beaten egg whites, beating continuously.
Continue to beat until the mixture thickens.
Add vanilla for flavor.
Use two-thirds of the mixture as white icing.
For the remaining third, add melted chocolate.
Shave the chocolate finely.
Place it in a cup over a pan of boiling water to melt.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the syrup that gives the icing its sweetness and smooth, glossy body.
- Egg whites
- Whipped to a foam that the hot syrup thickens into a light, set icing.
- Chocolate
- Melted into one portion of the icing to add flavor and color.
The step that matters
Pour the hot syrup in a thin stream. Pouring the hot syrup slowly while beating keeps the egg whites from scrambling and lets the syrup cook them into a stable, thickened foam. Pouring it all at once can cause uneven clumps.
