Thanks for finding that recipe.
I know that the recipe is in the black book at the Jambo pool bar. I usually carry a copy of it with me just in case. Cat made a copy of the recipes for Nahtazu and Victoria Falls Mist for the book at Sanaa in December. When we had lunch there in April, the bartender couldn't find them. He called the Jambo pool bar, got the recipe and made me two Nahtazus.
Enjoy!
