HWC stands for Heavy Whipping Cream. Use fresh, real mozzarella, from a cheese log. Also, I cook it at 375 degrees. I think my oven might run hot…too high and the cheese browns too quickly and burns.
Next time I will use the entire cheese log, full 16 ounces. I sliced it a bit too thin on the casserole above. I had cheese leftover. Also, I took it out of the oven a couple minutes early. You have to watch it and take it out before the cheese burns.
