Not SaltedFig but soleseifes generally still lather quite well. My first one had nice, dense lather even at only 4mos cure so I imagine it'll be awesome at 12. Most recipes will work but some up the coconut slightly to help with bubbles. And/or some form of milk. I think I even remember using a bit of sugar.. A tweak of this recipe was my first but I've since experimented with salt amounts, additives, etc. Some inspired partly from the experiments from this german site. Oh btw, I came across this experiment and was surprised how long a soleseife bar can last.
