Why it works: Milk and butter are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Butter Fondant
Ingredients
Directions
Combine sugar, cream of tartar, and milk in a saucepan over gentle heat.
Stir until sugar dissolves.
Boil without stirring until it reaches the soft ball stage (238°F).
Add butter when the syrup is nearly done.
Pour onto a warm, buttered platter and finish as fondant.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the sweet syrup base that crystallizes into the fondant's texture.
- Cream of tartar
- Acidifies the syrup to help prevent unwanted sugar crystals from forming.
- Butter
- Adds fat for a softer, smoother texture and richer flavor.
The step that matters
Boil without stirring to the soft ball stage. Stirring during boiling can trigger premature sugar crystallization, leaving grainy fondant. Stopping at the soft ball stage, 238°F, controls how much water evaporates and sets the final firmness.
