Carefully combine the lye and coffee by pouring the lye into the coffee (never pour liquid into the lye) and stir liquid until lye is completely dissolved. The liquid is caustic and not to be touched in anyway. The outside of the bowl will be extremely hot as well. Be careful when working with lye and follow all of the recommended precautions. Note: What I’m trying to say is, I can not be held responsible for any craziness, mishaps, explosions, etc. that may happen when making this recipe.
