Sorry, but I have to disagree on many levels here (and agree in many others)
I personally think, there are too many rubbish lathering tutorials and so called experts out there - that's the real problem.
I have seen so much crap lather and so many BS methods on how to get the above...it is simply mind boggling.
You can get a fantastic lather out of the Fat and many other so called difficult products - you just have to do it the right way.
Start with a damp brush, load on the puck, add a couple drops of water to the puck or brush as soon as nothing happens.
Continue, until you have fantastic glossy lather. If this method does not work - your soap is not a shaving soap - else it works - and it definitely works with the Fat.
Everything else is either a case of misguidance (see above about experts), impatience (too much water to quickly), stinginess (not enough product) or a mixture of the above.
And yes, I love Pork-Chops
