I think coconut oil would be pretty difficult to come by. The better option would be to go ahead and make the soap and store it away for later use. Coconut oil should make a nice hard bar, as opposed to say olive oil, so a batch should last a good long time.
I didn’t take it so much as her slamming lye as just making sure people understand that it can be dangerous. Though why you wouldn’t know that I have no idea. I guess the alternative could be to make your own ash, but then the ratios change. But, I suppose that lye would get hard to come by also, so would be good to have that knowledge and skill.
Good points! Thx.
