It’s been many years since I learned the ins and outs of percentages, ratios and parts. I get plenty of practice playing with them though since almost every day is a soap day around here (lucky me!). It is one of the more common questions that our stupendous team gets whenever soapers are trying to calculate parts (whozit? whatzit?!), resize batches or try to figure out if they have too much (or too little) coconut oil in their recipe.
