flop - The trick is to cook one side, slide your spatula under and then rotate the arm (it moves 360 degrees) and flip it over while keeping it still in the silicone mold. Only remove the mold once the second side has cooked pretty well. (We also sprayed the silicone with cooking spray as an added protection)
Success!
Of course for Valentine's Day - you could sprinkle pwd sugar over them, add a flag that says "love" or anything else! Enjoy!
