Grandma Ruby's Fabulous Fudge

This is a classic chocolate fudge using the marshmallow shortcut method, sometimes called See’s-style or Fantasy Fudge. Boiling sugar and evaporated milk for a precise 6 minutes does the structural work, while the marshmallows below provide instant emulsification when the hot syrup hits them.

The marshmallow trick is why this recipe is nearly impossible to mess up. Traditional fudge requires hitting the soft-ball stage at 234°F (112°C) and beating it through the right cooling window. This version skips all of that by leveraging the gelatin and sugar in marshmallows to give a creamy texture every time.

The 24-hour cure in a cool place is not optional. Fudge needs that time for the sugar crystals to settle into a fine, even structure. Cutting earlier gives a grainy or soft batch.

Pro Tips

• Time the 6-minute boil from when the mixture reaches a true rolling boil that cannot be stirred down, not from when bubbles first appear.
• Use a heavy-bottomed pot. Thin pans scorch the milk and tint the fudge.
• Toast the nuts first. Raw nuts taste flat against the rich chocolate base.
• Line the pans with parchment hanging over the sides for easy lift-out and clean cutting.

Variations

• Use walnuts, pecans, or a mix of both. Walnuts have a slight bitterness that balances the sweetness.
• Swap milk chocolate for half the chips for a sweeter, lighter fudge.
• Add a teaspoon of espresso powder to the sugar mix for a mocha version.
