01 - Line a baking sheet with parchment paper and set aside.
02 - Combine the chocolate and coconut oil (if using) in a heatproof bowl. Melt over a pot of simmering water, stirring constantly until smooth and glossy. Alternatively, microwave in 20-second bursts, stirring between each interval.
03 - Hold each strawberry firmly by the green stem. Dip into the melted chocolate, rotating to coat approximately two-thirds of the berry, allowing excess chocolate to drip off.
04 - Immediately sprinkle or roll the chocolate-dipped portion in the chopped nuts, pressing gently to ensure adhesion. Shake off any loose excess.
05 - Transfer the coated strawberries to the prepared baking sheet. Allow chocolate to set at room temperature for 30 minutes, or refrigerate for 10 to 15 minutes until firm.
06 - Serve immediately or refrigerate in a single layer for up to 24 hours. For optimal texture and flavor, consume within the same day of preparation.
