Bark is one of the easiest things to make. Just ask any tree. All you need is a microwave and a fridge. And some chocolate.

Preparation: 5 minutes
Cooking: 5 minutes plus 2 - 4 hours chilling time

Ingredients
800g good-quality 60% cacao semi-sweet chocolate, chopped
155g roasted unsalted almonds, chopped
155g roasted shelled pistachios, chopped
½ tsp pure vanilla extract
1½ tsp coarse flake sea salt

Method

Line a baking sheet with parchment paper.

Place the chocolate in a microwave-safe bowl and melt it in a microwave in 10-second intervals, stirring often, until smooth. Add 60g of the almonds, 60g of the pistachios, and the vanilla and stir well to coat the nuts.

Use a rubber spatula to spread the mixture evenly on the prepared baking sheet.

Sprinkle the salt and the remaining almonds and pistachios over the top.

Cover and refrigerate until the chocolate is set, 2 to 4 hours.

Break the bark into pieces and store in an airtight container with parchment or wax paper between the pieces.

The bark can be stored for about 1 week.
