It sounds like you’ve come across a unique twist on the traditional Italian sweet, tette della monache. The term "African mix" isn't commonly
associated with Italian baking, so it might be a specific blend of spices or a misinterpretation in the recipes you found. If you're aiming for authenticity, I’d recommend using classic ingredients like flour, eggs, sugar, and custard. For clarity on the "African mix," you might consider contacting the recipe’s author directly.
