Screwed Up Making Sepp Holzers Bone Sauce. Need Advice.

So I followed the instructions on the youtube video where Sepp Outlines how to make bone sauce. Three problems occured... There was still a significant amount of water in the pot when I finished the fire, even after burning it for about 2.5 hours. Also, some soil got into the pot as I was in the process of getting the top pot with the bones off, and I left it in there. I took the pot with the bone sauce water inside thinking that some of the water would evaporate. The big problem is that ALL of the water evaporated and now there's nothing left but soil and a tiny amount of dried up flakes at the bottom of the pot. The smell is strong so the bone sauce compound is there in at least some small amount.

So my idea is to just add some cooking oil, mix it with whatevers left in the bottom of the pot, and use that on the trees. The problem I see is that the soil will just wash away with the next rain, and all this work of making the bone sauce and painting the tree will be for nothing. Should I just leave it at "It's worth a try" and go for it, or do you have another suggestion as to how to fix this?

Thanks for your time and attention.

I don't know much about the sauce but could you somehow reconstitute it with the oil and then filter it through a coffee filter or a fine metal strainer? I think I recall talk about adding quartz sand being added to the sauce as a way to make the stuff even less pleasant to get in your mouth. I know I hate sand in my food. so maybe the soil isn't a problem at all. My impression was that the smell/taste is absorbed by the tree bark and thus becomes near impossible to wash off anyway. Hope that helps in some way.

I would imagine that it'll work to some degree regardless of the variables you have.
