Best Fudge

Ingredients

Directions

Make the candy

  1. Combine sugar, cream, and cold water in a hot water pan of a chafing dish.

  2. Stir until sugar melts.

  3. When the mixture begins to bubble, stir in cocoa or chocolate.

  4. Let it boil for exactly 6 minutes with the flame at half strength.

  5. After 6 minutes, add butter.

  6. Stir well, ensuring the candy doesn't stick to the pan.

  7. After the butter has boiled for 3 minutes, extinguish the flame.

  8. Add vanilla.

Finish and set

  1. Beat the candy until it thickens rapidly, about 1 minute.

  2. Pour into a buttered tin.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Granulated sugar
Provides sweetness and, as it dissolves and cooks, forms the crystalline structure of the fudge.
Cream
Adds fat and richness, giving the fudge a softer, creamier texture.
Cocoa or chocolate
Supplies the chocolate flavour and colour of the fudge.
Butter
Adds fat for smoothness and a tender, glossy texture.

The step that matters

Beat the candy until it thickens rapidly. Beating while the cooked sugar mixture cools controls crystal formation. Too little beating leaves the fudge soft and runny, while beating too long or after it has set can make it grainy and hard to pour.

Swap the cocoa

How well each one fits the dish's main ingredients (sugar, cream, butter, vanilla):

  1. Almondfits better
  2. Chestnutfits better
  3. Hazelnutfits better
  4. Cocoathe original

Fit is the average pairing score against sugar, cream, butter, vanilla. Candidates are from the same food group and used in at least 100 recipes.
