Oh yeah I should have linked it lol. It's this forum's very own calculator! There's info on each fat there too, you can read while inputting em. I mainly pay attention only to the cleansing n longevity numbers btw.
In the link I gave you in my earlier post, there's a good read on water/lye ratio in one of the pages. I usually use 2.8:1 for HP...
Also, smallest recommended batch is about 500 grams, but unless your scale can handle decimals, and you can pour exactly that amount I guess you can try smaller. Oh, and if your HP vessel still lets you submerge your stick blender...
Aahh, wonderful calculator!! I am so tempted to just start straight away with HP, but so scared at the same time to fail and waste everything... let’s see what my mind settles onto! Thanks a lot for your help
