Thank You: Droste's Hot Cocoa (recipe from the tin, 1900's)

Thank you, Betsy ! This is the second time that you have found something obscure for me.
The last time you found a recipe for Triplet Cookies that my mother had taken from a magazine and that we had lost. Many years later I actually found the actual clipping from the magazine at my mother's - but I had been able to make them meanwhile thanks to you.
