Why it works: Milk and butter match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 81,222 recipes mention both. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
In a saucepan, combine sweet milk, sugar, cinnamon, and butter.
Bring the mixture to a boil.
In a small bowl, dissolve corn starch in a little cold water.
Stir the dissolved corn starch into the boiling mixture.
Cook over simmering water until thickened.

Sugar and cinnamon share little aroma chemistry, yet 30,777 recipes mention both: they likely 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
- Sweet milk
- Forms the liquid base of the sauce and carries the other flavors.
- Corn starch
- Thickens the sauce as it heats, giving it body.
- Sugar
- Adds sweetness and balances the flavor of the cinnamon.
- Butter
- Adds richness and a smooth mouthfeel to the sauce.
The step that matters
Stirring the dissolved corn starch into the boiling mixture. Cornstarch must be fully dispersed in cold liquid before it meets heat; adding it lumpy or undissolved causes clumps. Stirring while it enters the hot liquid keeps the starch evenly distributed so it thickens smoothly as the starch granules swell.
