Line a 5” square tin with parchment paper with over hanging edges.
Melt chocolate until there are no lumps left. You can either use your microwave oven or a double boiler to melt the chocolate.
Heat up the condensed milk separately. You can either use microwave oven or a double boiler.
Add the warm condensed milk to melted chocolate and whisk to combine.
Over mixing will split the chocolate, so make it swift. The mix will thicken as you mix. Once they both are thoroughly combined, stop mixing.
Add pistachios and cranberries to the fudge mix and fold it with a spatula.
Transfer to the prepared tin and level the top.
Refrigerate for two hours or until set and firm to touch.
Remove the fudge from the tin using the overhanging edge of the paper.
Slice it into squares with a sharp knife.
Store the fudge in a box in fridge.
