01 - Line a baking sheet with parchment paper and set aside for later use.
02 - Peel pears while keeping stems intact. Trim a thin slice from the bottom of each pear to enable upright standing.

05 - Place coated pears upright on the prepared baking sheet.
06 - While chocolate remains soft, sprinkle with chopped pistachios, nuts, or edible petals as desired.
07 - Drizzle melted white chocolate over pears for decorative finish.
08 - Refrigerate pears for 15 to 20 minutes until chocolate is completely set.
09 - Serve immediately or maintain refrigeration until ready to serve.
