Melt the chocolate and coconut oil together in a heatproof bowl set over a pan of simmering water, stirring until smooth. Or, do this in 30-second bursts in the microwave. Remove from the heat and cool slightly.

For the filling, stir the pistachio butter, tahini and shredded coconut together in a small bowl until well combined – the mixture should be thick but spoonable. If it's too dry, stir in a little more pistachio butter.

Spoon about 1 tsp melted chocolate into each of 12-16 mini silicone moulds or mini cupcake cases, tilting back and forth to coat the sides. Chill in the freezer for 5 mins to set slightly.

Spoon a small dollop of the pistachio mixture into each chocolate-lined mould, flattening it gently using the back of the spoon. Top with more melted chocolate to cover the filling, then sprinkle over the chopped pistachios and a pinch of salt. Chill in the fridge for 20 mins until fully set.

Pop the chocolates out of the moulds and serve. Will keep in an airtight container in the fridge for up to a week.
