I think this is the correct link.
Yes, that is the recipe that I have. I forgot to mention that the first time I did it as stated in the recipe (2 Tbsp. butter and 2 Tbsp. glycerin). Then somewhere on here I came across the version with 3 Tbsp. each butter and glycerine and did that on the second batch. For try 3 I am doing the 2 Tbsp. version since that is what she states is correct and I'm just going to make sure that a) my cream isn't too cold and b) that I have plenty of time to just let the hot mixture cool on its own without having to resort to a water bath. The humidity here (south Louisiana) probably doesn't help matters, but I'll check the weather before making a batch.
