01 - Line a baking sheet with parchment or wax paper and set aside.
02 - In a heatproof bowl, melt the dark chocolate over a saucepan of simmering water using the double boiler method, stirring constantly until smooth. Alternatively, microwave in 20-second bursts, stirring between each interval, until fully melted and glossy.
03 - Hold each strawberry by the stem and dip into the melted chocolate, swirling gently to coat approximately 3/4 of the berry.
04 - Immediately sprinkle the chopped nuts over the chocolate-coated section while the chocolate is still warm, or dip the berry into a bowl of nuts for heavier coverage.
05 - Place the dipped strawberries onto the prepared baking sheet, ensuring they do not touch each other.
06 - If using white or milk chocolate, melt it using the same method and drizzle over the dipped berries for decoration.
07 - Let the chocolate set at room temperature for approximately 30 minutes, or refrigerate for 15 minutes for faster setting.
08 - Serve immediately or store in the refrigerator for up to 24 hours.
