395g can sweetened condensed milk
1 1/2 cups brown sugar
80g butter, chopped
75g pecans, chopped
200g white chocolate, chopped
200g dark cooking chocolate, chopped
60g Copha, chopped
Extra 100g pecans, finely chopped
Line base and sides of a large loaf tin with baking paper. Put condensed milk, sugar and butter in a medium heavy-based saucepan and stir to combine. Cook, stirring continuously with a wooden spoon, over medium heat for 12-15 minutes or until mixture thickens and becomes a caramel colour.
Add chopped pecans and stir to combine. Remove pan from heat and stand for 5 minutes. Add white chocolate and stir until melted and combined. Pour mixture into prepared tin and allow to cool slightly. Chill for 1 hour or until mixture is firm.
Put dark chocolate and Copha in a heatproof bowl and stir over a pan of simmering water until melted and smooth. Remove fudge from tin and divide mixture into 3 long strips. Set fudge aside to soften for 20 minutes, then roll each strip into a log shape.
Put extra pecans on a sheet of baking paper. Dip logs into chocolate and spoon over top, making sure logs are completely covered. Roll each log in nuts. Transfer to a wire rack and sit over a tray until set. Cut logs into 1 cm-thick slices to serve.
