As a hobbyist I have had the same issues. Keep a close eye on it and remove the pan every time it starts to "explode" or foam up. It may take a few times to settle. Turn down the burner slightly as well. A little smeared butter on the to part of the pot slows it down as well. Also a drop of vegetable oil works. Usually when it does this it is very close or past syrup. Good luck.
