Wellesley Marshmallow Fudge
Ingredients
Directions
Make the fudge
Heat 2 cups of granulated sugar and 1 cup of rich milk (cream is better).
Add 2 squares of baker's chocolate and boil until it hardens in cold water.
Just before it is done, add a small piece of butter and begin to stir in marshmallows, crushing and beating them with a spoon.
Continue to stir in marshmallows after the fudge has been taken from the fire until one pound has been stirred into the fudge.
Cool and cut
Cool in sheets 1 inch thick and cut into cubes.

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 body of the fudge.
- Rich milk
- Adds moisture and richness, helping the sugar form a smooth, creamy texture.
- Bakers' chocolate
- Adds chocolate flavour and fat, firming the fudge as it cools.
- Marshmallows (in the method)
- Stirred in off the heat, they add softness and a light, creamy texture to the fudge.
The step that matters
Stirring in the marshmallows after the fudge leaves the fire. Adding marshmallows while the mixture is still very hot lets them melt fully into the fudge. Stirring them in off the heat keeps the mixture smooth and helps it set with a fine, creamy texture.
