Earl-Grey Truffles

In a small saucepan, stir together cream and tea over medium heat. Bring just to a simmer, then let mixture continue to gently simmer 5 minutes. Remove from heat and let cool completely. Place chopped chocolate in a heatproof bowl.

Pass cream mixture through a fine-mesh sieve into a clean saucepan. Bring to a boil, then pour over chocolate and let stand 3 minutes. Stir until smooth, then stir in butter and vanilla. Refrigerate until set, at least 30 minutes or, covered with plastic wrap, up to 2 days.

Place cocoa in a bowl. Scoop mixture with a level teaspoon, then dust hands with cocoa and roll truffles into balls. Coat your hands with a bit of melted chocolate and roll truffles in your hands to lightly coat to create a "shell".

Drop truffles into bowl of cocoa; toss to coat. Refrigerate in an air-tight container until ready to serve, at least 30 minutes and up to 1 week. Let stand at room temperature 15 minutes before serving.
