Nanny, Your post makes it sound like you are testing the USA. If this is the case you might want to add it to the wax as you use it till you decide if you are going to continue. If you add it to the batch and then don't like it.... you have a bunch of "junk" wax to deal with. If you have your formula all settled, I'm with Stella.... dump it in, one less thing to mess with later!! Have fun with that turkey fryer!!
