Why it works: Sugar and cream are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 43,450 recipes. Both carry 2,3-butanedione, which smells butter, sweet. The science ↓
Favorite Fudge
Ingredients
Directions
Make the syrup
In a saucepan, combine sugar, glucose, and water. Bring to a boil.
Slowly add the condensed milk without stopping the boil.
Continue boiling until it reaches the medium ball stage.
Finish the fudge
Remove from heat and stir in the cream fondant until melted.
Add flavoring and nuts or fruit if desired.
Set and mark
Let the mixture stand for about 5 hours.
Mark the fudge with a sharp knife by drawing it across the surface quickly.
If the fudge is too soft, place it in a dry, warm area for a while.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Sugar
- Forms the sweet, firm body of the fudge as it crystallizes during cooling.
- Glucose
- Interferes with large sugar crystals, helping the fudge stay smooth rather than grainy.
- Condensed milk
- Adds milk solids and fat for a creamy, soft texture and rich flavor.
- Soft center cream fondant
- Adds fine sugar crystals that encourage a smooth, tender texture.
The step that matters
Continue boiling until it reaches the medium ball stage. The final sugar concentration, set by the cooking temperature, determines firmness. Stopping early leaves the fudge too soft to hold its shape, while overcooking makes it hard and crumbly.
Swap the nuts
The recipe marks nuts as optional. How well each one fits the dish's main ingredients (sugar, condensed milk, cream):
- Almondfits better
- Pistachiofits better
- Hazelnutfits about as well
- Nutsthe original
Fit is the average pairing score against sugar, condensed milk, cream. Candidates are from the same food group and used in at least 100 recipes.
