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 ↓
Butter Creams
Ingredients
Directions
Make the syrup
Combine sugar and cold water in a saucepan.
Stir slowly with a wooden spoon until dissolved.
Bring mixture to a boil, then add a pinch of cream of tartar.
Do not stir again.
Wash down any sugar that forms on the sides of the pan with a damp rag.
Cook until mixture reaches soft ball stage when dropped in cold water, then remove from heat.
Cool and work the fondant
Pour mixture onto a platter and let it cool.
Once cool, beat with a wooden spoon until creamy.
If mixture becomes too hard, wrap it in a damp cloth and knead like bread.
Work in butter to taste and add vanilla extract before it hardens.
Form mixture into small balls and let them sit for a few minutes.
Coat and store
Melt chocolate in a double boiler.
Dip each ball in chocolate using two forks, then place on oil cloth or wax paper to harden.
Store fondant in a stone jar with a damp cloth on top to keep it fresh for weeks.

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
- Forms the sweet crystalline body of the fondant once it is cooked and worked.
- Cream of tartar
- Acid that helps prevent sugar from recrystallizing into a grainy texture.
- Butter
- Adds fat that makes the fondant softer and creamier.
- Chocolate
- Forms a sweet, firm outer coating on each fondant ball.
The step that matters
Do not stir after the mixture boils. Stirring a boiling sugar syrup can cause sugar crystals to form, leading to a grainy rather than smooth fondant. Washing down crystals on the pan sides with a damp rag helps prevent this.
