I recently lathered Sterling's Mutton tallow soap. Ironically, its lather is very much like Shannon's soap lather. The beef tallow Stirling takes on water in a different way. Shannon's and the mutton tallow Stirling don't incorporate the water as much as they hold on to it. The lather becomes very wet, dense and somewhat low volume. I don't know how to describe it well, but it is the kind of lather that you can fling across the room. It is also possible that my results are atypical. I am not really used to these soaps, but in my experience they are both slick and create an lather that is specific to them. If you wind up using Shannon's, please let us know your results.
