3/4 cup condensed milk
2 cups coconut (desiccated or fresh grated)
4 tbsp melted butter
3 tbsp raisins (or dried black currants)
Combine all four ingredients in a bowl and mix until well-incorporated. Scrape the mixture into a greased baking pan and bake at 165C for 1 hour.
Increase the temperature to 185C and bake for another 10 minutes to form a crisp top. Remove from oven and cut into bars. Leave to cool in pan. Once cool down, run a knifeover the bars or break into pieces.
