I want to share that my "favorite" recipe has changed over time for various reasons. I don't know of too many other soap makers who are still using the same recipe they started out with. The only exception was my grandmother who always made 100% lard soap for her laundry.
After about a year or so of experimenting and being mentored by my soap maker friend Renae, I arrived at a blend of fatty acids that works pretty well for me. So the fatty acid percentages in my recipes tends to be similar from batch to batch, but the fats I use to get those proportions can vary.
I like a little bit of avocado, for example, but it's a high oleic oil so if I don't have avo, I'll simply replace it with more high oleic sunflower, which is my main high-oleic oil (as opposed to olive).
Other shifts in my recipe: If my friend Renae gives me some rendered tallow, I'll sub in tallow for some of the lard I normally use. I used to use shea, but trials with and without shea showed me there's not a huge difference, IMO.
So keep an open mind about your "standard" recipe.
