Hi Melanie! What brand of emulsifying wax did you use? Do you have a link to it? Some emulsifying waxes are stronger than others, so you might need to increase the amount for some, depending on how recipes turn out.
There are also a few products out there labeled emulsifying wax, but they’re not complete emulsifiers & don’t work well on their own. If you let me know, I’ll be happy to take a look at the one you used! :)
