I'm trying to learn how to make edible lace for my parents 50th anniversary cake. I've decided to learn to make it rather then buy and one recipe I found uses glycerine. I then found out I can make my own glycerine and use the soap that it seperates from... win win! However, I tried using the wikihow instructions today and the glycerine never separated from the soap. At first i thought it was because the salt didn't fully desolve, i tried putting it back on the stove to heat it up and further desolve the salt... but that didn't seem to work either. Any suggestions or tips? Can I save what I've done thus far by reheating?
