The need for cooking isn't all that surprising then, EVOO is a slowbie. What I'm more surprised by is that you're amazed by the amount of lather? Can we get a picture? My EVOO LSs are almost like washing yourself with water, appearence and feel wise.
On the other hand, I can see what you mean on both points :?. I recently made a batch out of used (cleaned) frying oil (french fries), 100% sunflower. I only used heat until reaching paste, and the end bubblyness also surprised me a bit. It's no coconut soap, but still.
Side note: I also added a hefty amount of inverted sugar syrup (water+sugar+citric acid cooked until the sucrose breaks down to fructose and glucose (better humectant properties and shelf life and doesn't recrystalize) to a part of the diluted 100% sunflower soap. Basically replicating Bronner's pump/shikakai soap, except I don't have a clue how much of the syrup they add, or when. Anyway, this COMPLETELY annihilated all the bubblyness it had before. Probably added way too much of the sugar, like 1:1. Again, it's like washing with water.
