In a small saucepan, melt the butter. Add heavy cream and stir to combine. Stir in salt, orange extract, and food coloring (if using) and mix again to combine. Set aside, but make sure this mixture is approximately the same temperature as the melted chocolate before combining them.

Over a double boiler, melt the chopped white chocolate, stirring occasionally until smooth and completely melted. Be very careful not to overheat the chocolate - it should not be heated above 105°F (it should feel about the same temperature as your body when touched with your finger), or the chocolate will separate and be unusable.

Gently stir the lukewarm butter and heavy cream mixture into the melted chocolate until fully incorporated and smooth.

Cool the mixture slightly, then cover with plastic wrap and refrigerate for 2-3 hours, or until firm enough to roll into balls. While it's cooling, you can occasionally take it from the fridge, stir with a fork, cover again with plastic wrap, and place back into the refrigerator.

With a small spoon or a melon baller, scoop out the mixture and roll into 1-inch balls. You can dust your hands with powdered sugar, or if the mixture is too sticky, drop a spoon of mixture into powdered sugar (this makes it much easier to roll into a ball).

Roll each ball in powdered sugar to coat well.

Store the truffles in an airtight container in the refrigerator for up to 1 week, or freeze for longer storage.
