Notes
Make sure to use high quality chocolate for the best results for these lemon truffles. You can roll the truffles in sprinkles instead of the powdered sugar before serving if you prefer. Make sure that you stir the mixture with either a wooden spoon for the best results as it helps move the heat evenly throughout the mixture. Store any leftovers in an airtight container for up to 4-5 days.
