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, as it cooks with milk, builds the caramel flavour and firm texture of the fudge.
- Milk
- Supplies moisture and dissolves the sugar, forming the base that cooks down into a creamy fudge.
- Butter
- Adds fat for a smooth, rich mouthfeel and helps keep the fudge tender.
- Maple syrup
- Adds maple aroma and extra sweetness, along with some moisture.
- Walnuts
- Add crunch and nutty flavour that contrasts with the smooth fudge.
The step that matters
Cook until the mixture hardens when dropped in water. Cooking drives off water and concentrates the sugar until it reaches the right point. Too little cooking leaves fudge soft and runny, while too much makes it hard and grainy. The water test is a practical way to judge that point.
Swap the walnut
How well each one fits the dish's main ingredients (sugar, milk, egg, butter, maple syrup):
- Pecansfits better
- Almondfits about as well
- Walnutthe original
- Nutsfits about as well
Fit is the average pairing score against sugar, milk, egg, butter, maple syrup. Candidates are from the same food group and used in at least 100 recipes.
