I made 100% lard soap. Yay! the process went pretty well. I waited for a day to cut them and when I did I noticed in the middle there are white swirls in my soap! What on earth? Is it partial gelling?
No it is not bad, it is just cosmetic. With palm oil, melting down the whole container and stirring well helps distribute the stearic acid throughout the palm oil. It might help with lard, I don't know. Personnally I wouldn't worry about your bars, they look great.
