Step 1: Mix Mix the sugar and cocoa together in the large saucepan. Then add the corn syrup and evaporated milk.
Step 2: Cook Cook the mixture over medium heat, stirring until it reaches 234 to 240 degrees Fahrenheit on a candy thermometer. Remove from heat.
TIP: Test for doneness by dripping a small drop of the mixture into cold water. If it forms a soft ball, it's done.
Step 3: Add butter Stir the butter and vanilla into the fudge mixture and beat thoroughly.
TIP: You can also add chopped walnuts or pecans.
Step 4: Transfer to dish Pour the fudge immediately into a buttered, rectangular glass dish – the mixture hardens quickly. Use a spatula to spread it evenly in the dish.
Step 5: Set, cut, and serve Allow the fudge to set for a few hours, and then cut it into squares and serve. Fudge can be refrigerated in an airtight container for up to 1 week.
FACT: Composer and fudge enthusiast Cole Porter had a standing order for 9 pounds of fudge to be shipped to him monthly.
