01 - Line a baking sheet with parchment or wax paper and set aside.
02 - Place chopped dark chocolate in a heatproof bowl over a saucepan of simmering water, stirring until smooth. Alternatively, microwave in 20-second bursts, stirring between each interval until fully melted.
03 - Hold each strawberry by the stem and dip into the melted chocolate, swirling to coat approximately 3/4 of the berry.
04 - Immediately sprinkle chopped nuts over the chocolate-coated section, or dip the berry into a bowl of nuts for heavier coverage.
05 - Place each dipped strawberry onto the prepared baking sheet, ensuring they do not touch each other.
06 - If using, melt the white or milk chocolate and drizzle over the dipped berries for decorative finish.
07 - Allow the chocolate to 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.
