Directions

1. Use 2 glass bowls set over 2 saucepans of boiling water, making sure that the water doesn't touch the bottoms of the bowls. Melt the dark and milk chocolates in 1 bowl and the white in the other. Stir both until smooth, then add the mint essence to the melted dark and milk chocolate.
2. Line a baking tray with baking parchment. First, pour a little of the dark and milk chocolate onto the paper, spaced apart, then pour the white chocolate on top. Using a knife, swirl the chocolates together to create a marbled effect. Arrange the pretzels on top of the chocolate and leave to harden. Break into pieces and serve. Will keep for 1 week in an airtight container.
