01 - Line a baking sheet with parchment paper. Verify strawberries are completely dry to prevent chocolate from seizing.
02 - Place chopped dark chocolate in a heatproof bowl set over a saucepan of simmering water. Stir continuously until completely smooth and glossy. Alternatively, microwave in 20-second intervals, stirring between each burst.
03 - Hold each strawberry by the green stem and dip into melted dark chocolate, swirling to coat two-thirds of the berry. Gently shake to remove excess chocolate and transfer to prepared baking sheet.
04 - Using the same double boiler method or microwave approach, melt white chocolate until completely smooth, ensuring no water contamination.
05 - Transfer melted white chocolate to a piping bag or small zip-top bag with a tiny corner snipped off for precise drizzling.
06 - Pipe white chocolate in thin parallel lines or decorative zigzag patterns over chocolate-coated strawberries while dark coating is still slightly tacky.
07 - Allow chocolate to set at room temperature for 20-30 minutes until firm. For quicker setting, refrigerate briefly. Serve immediately or store in single layer in refrigerator up to 24 hours.
