I make it using the Merckens brand chocolate. I use 1 - 16 oz. bag Merckens and 1/2 cup white corn syrup. I really like the way Merckens melts -- smooth and creamy. Melt chocolate then add the corn syrup. Stir until combined. Wrap in plastic wrap. If I need it soon, I put it in the fridge to harden. Best results are letting it set overnight.
