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 ↓
Maple Fudge
Ingredients
Directions
In a saucepan, combine brown sugar, maple syrup, sweet milk, and butter.
Bring to a boil and cook until a small amount dropped into a cool dish forms a soft ball.
Remove from heat and stir in chopped walnuts until creamy.
Pour the mixture into a buttered pan and mark into squares.
Set aside to cool.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Brown sugar
- Provides sweetness and molasses flavour, and helps set the fudge's soft texture.
- Maple syrup
- Adds sweetness and maple aroma, and its sugars help keep the fudge smooth.
- Sweet milk
- Adds moisture and richness, and its milk solids contribute to a creamy texture.
- Chopped walnuts
- Add crunch and nutty flavour that contrast with the soft, creamy fudge.
The step that matters
Cooking to the soft-ball stage. Sugar concentration determines the final texture. Cooking too little leaves the fudge runny, while cooking too long makes it hard and grainy. A small sample dropped into cool water or a cool dish shows when it has reached the soft-ball stage.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, maple syrup, milk, butter):
- Pecansfits better
- Almondfits about as well
- Walnutthe original
- Nutsfits about as well
Fit is the average pairing score against sugar, maple syrup, milk, butter. Candidates are from the same food group and used in at least 100 recipes.
