Oxy Fudge

This is real, old-fashioned cooked fudge, not the shortcut condensed-milk kind. A sugar and evaporated milk syrup gets boiled for a precise 14 minutes, then poured over chocolate and butter and beaten at high speed until it transforms from a glossy liquid into a thick, creamy, spoonable mass. The result is dense, smooth fudge with that classic snap when you bite through and a slow melt on the tongue.

Timing the boil is everything. Start your 14-minute count only after the mixture hits a full, rolling boil. Undercooking leaves the fudge soft and sticky. Overcooking makes it grainy and dry. Stir occasionally during the boil to prevent the milk sugars from scorching on the bottom of the pan.

The 10-minute beating at high speed isn’t just mixing; it’s creating the fudge’s texture. The mechanical action develops tiny sugar crystals instead of large gritty ones, which is what gives you that smooth, creamy mouthfeel. Start on low to combine the hot syrup with the chocolate and butter, then crank it up. You’ll see the mixture go from shiny and thin to matte and thick. That’s when you know it’s ready.

Nuts and vanilla go in at the very end, stirred by hand so you don’t overbeat the fudge past its ideal consistency.

Pro Tips

• Use a heavy-bottomed saucepan. Thin pans create hot spots that scorch the milk before the syrup reaches the right stage.
• Grease your pan well before pouring. Fudge that sticks is fudge you can’t cut into clean squares.
• Let it chill completely before cutting. Room-temperature fudge will smear under the knife. For the cleanest cuts, use a sharp knife dipped in hot water.

Variations

• Peanut butter marble: Swirl warm peanut butter through the fudge right after pouring into the pan for a chocolate-peanut butter combination.
• Espresso fudge: Dissolve a tablespoon of instant espresso powder into the hot syrup before pouring over the chocolate for a mocha edge.
