Rewarm the coconut-infused mixture. Place a mesh strainer over another medium saucepan and strain the coconut-infused liquid through the strainer into the saucepan. Press down on the coconut very firmly with a flexible rubber spatula to extract as much of the flavor as possible. Remove the vanilla bean halves and reserve both it and the coconut for another use.☞ TESTER TIP: What to do with that leftover coconut? Spread it on a parchment-lined rimmed baking sheet, toast in the 350°F oven until golden brown, about 10 minutes. Then sprinkle it atop the ice cream before serving. You'll want to stash any extra toasted coconut in the fridge.
