<p>I think the double boiler is the key! I could never make it work in a normal pan, but now I fill a small pot with water and sit inside it a metal bowl with rounded bottom. The bark melts nicely. I was doing oreo balls last night and it was my best-looking batch by far!</p>
<p>I have read that you can add a little Crisco to make it ‘runnier’ when needed. Good luck! If you find a better solution please report back!</p>
