01 - Line a baking sheet with parchment paper to prevent sticking.
02 - Place chopped chocolate in a heatproof bowl and melt over simmering water using a double boiler, stirring until smooth. Alternatively, microwave in 20-second intervals, stirring between each.
03 - Hold each strawberry by the stem and dip into the melted chocolate, swirling to coat evenly. Allow excess chocolate to drip off.
04 - Immediately sprinkle the dipped strawberries with chopped pistachios or press them into the nuts for a thicker layer.
05 - Place coated strawberries on the prepared baking sheet in a single layer.
06 - Let the chocolate set at room temperature for approximately 30 minutes or refrigerate for 10–15 minutes to speed setting.
07 - Serve immediately or keep in an airtight container refrigerated for up to 24 hours.
