I do a lot of all lard soap, usually with GM. It's a bit like all olive in that it suds best in warm to hot water and works best with a scrubbie or wash cloth. ( which i state on the label). I do discount the water which makes a difference. The suds are slower but it lasts longer. I add sugar which helps and I lower the supperfat like in my olive soaps to no more than 4% often lower.
I have a lot of repeat buyers on lard soaps once I get them to try it. They seem to be like 100% olive in this way also.
