Grapefruit Vanilla Bean Truffles

Directions

1. 1
   Finely chop white chocolate and place in a heatproof bowl. Set aside.
2. 2
   Add grapefruit zest to cream in a small heavy saucepan and bring to a simmer, taking care not to boil. Remove from heat.
3. 3
   Add butter and salt to white chocolate, then pour hot cream mixture into bowl. Melt over a saucepan with simmering water until smooth (do not allow water to touch glass bowl). Add vanilla bean seeds and grapefruit juice and stir to combine. Chill mixture for at least 4 hours.
4. 4
   Using a teaspoon or a small cookie scoop portion out 1-inch balls of ganache mixture. Roll in your hands to form a ball (quickly, as it will begin to melt from the heat of your hands). Immediately sprinkle each truffle with the sanding sugar and place on a parchment-lined baking sheet.
5. 5
   Allow to set in the refrigerator for at least 5 minutes before serving (will keep for up to 2 weeks when stored in an airtight container).
