Ingredients
Method
- Line an 8x8-inch pan with foil or parchment paper, leaving some overhang on two sides so you can lift the fudge out later. Lightly butter the lining.
- Put the chocolate chips, sweetened condensed milk and butter in a medium heavy saucepan over low heat. Stir constantly with a rubber spatula until the chips are completely melted and the mixture is smooth and glossy, about 4 to 5 minutes. Don't rush it with higher heat, or the chocolate can scorch and turn grainy.
- Take the pan off the heat and stir in the vanilla and salt, then fold in the walnuts.
- Scrape the fudge into the lined pan and smooth the top with the spatula.
- Refrigerate for at least 2 hours, until firm.
- Lift the fudge out of the pan using the overhang, peel off the lining and cut into 1-inch squares with a large sharp knife, wiping the blade clean between cuts.
Notes
Microwave method. Melt the chips, condensed milk and butter in a large microwave-safe bowl in 30-second bursts, stirring well after each, until smooth. Then continue with the vanilla, salt and walnuts.
Variations. Swap the walnuts for pecans, stir in 1/2 teaspoon peppermint extract instead of the nuts for a holiday mint fudge, or top with a sprinkle of crushed candy canes before chilling.
Storing and gifting. Keep fudge in an airtight container in the refrigerator for up to 2 weeks, with parchment between layers, or freeze for up to 3 months. Let it sit at room temperature for 15 minutes before serving.
Time. Total time includes 2 hours of chilling.
