01 - Line a baking sheet with parchment paper and fill a large bowl with ice and water to create an ice bath.
02 - Bring a medium saucepan of water to a boil. Gently lower the peeled pears into the boiling water for 1 minute, then immediately transfer them to the ice bath to stop the cooking process. Pat dry thoroughly with paper towels.
03 - In a heatproof bowl set over simmering water using a double boiler method, melt the dark chocolate with coconut oil or butter, stirring constantly until smooth and glossy. Remove from heat.
04 - Holding each pear by the stem, dip it into the melted chocolate, coating the lower two-thirds. Allow excess chocolate to drip off before placing the pear on the prepared baking sheet.
05 - While the chocolate is still wet, sprinkle each pear with chopped pistachios and a pinch of flaky sea salt if desired.
06 - Refrigerate the pears for at least 30 minutes until the chocolate coating is completely set.
07 - Remove from refrigerator and serve chilled or at room temperature as desired.
