Ingredients:
- 3 cups Granulated Sugar
- ¾ cup Unsweetened Cocoa Powder
- 12 oz can Evaporated Milk
- ½ cup (1 stick) Unsalted Butter, cubed
- 1 Tbsp Light Corn Syrup
- ½ tsp Kosher Salt
- 1 Tbsp Pure Vanilla Extract
Instructions:
- Prep the Pan: Line an 8x8 inch pan with parchment paper, allowing excess paper to hang over the sides. Lightly butter the paper.
- Combine Ingredients: In a heavy 4-quart saucepan, combine the sugar, cocoa powder, evaporated milk, cubed butter, corn syrup, and salt.
- Initial Heating: Place the pan over medium heat. Stir continuously until the butter is melted and the sugar is completely dissolved (the mixture should look uniform and not gritty).
- Washing the Crystals: Once the mixture begins to simmer, stop stirring. Use a pastry brush dipped in warm water to gently wash down any sugar crystals clinging to the sides of the pot. Do not stir after this point.
- The Boil: Insert the candy thermometer. Bring the mixture to a rolling boil and cook, undisturbed, until the thermometer registers 234°F (112°C) – the Soft Ball Stage.
- Remove from Heat and Add Vanilla: Immediately remove the saucepan from the heat source and quickly stir in the vanilla extract.
- The Cooling Trap: Place the saucepan on a cooling rack. Do not stir or disturb the mixture. Allow it to cool until the temperature drops to 110°F (43°C). Patience is key here—rushing this stage will result in grainy fudge.
- The Beating: Once the temperature reaches 110°F (43°C), begin beating the fudge vigorously with a wooden spoon or spatula.
- Watch for the Change: Continue beating until the fudge loses its glossy shine, becomes matte, thickens dramatically, and starts to hold its shape against the side of the pot (this usually takes 5–10 minutes).
- Set the Fudge: Working quickly, immediately pour the thick fudge into the prepared pan. Spread it evenly using the spatula.
- Chill and Cut: Allow the fudge to set completely at room temperature or chill in the refrigerator for at least 2 hours. Use the parchment paper handles to lift, peel off the paper, and cut into 36 small squares.
