The New Zealand company Griffin's makes 'Afghans', which are crispy
biscuits, flavoured with cocoa powder and with a milk chocolate
coating on top.
A recipe for a domestic version of Afghan biscuits evidently appeared
first in Edmonds "Sure to Rise Cookery Book".
The 1914 edition of this book is online at
http://www.nzetc.org/tm/scholarly/tei-EdmCook.html
Yet there is no recipe for Afghan biscuits in this edition.
The book has been through many editions since 1907.
Does anybody know when the recipe for Afghan biscuits first appeared?
Incidentally, there is no entry for Afghan biscuits in the Oxford
English Dictionary. Does anybody know of a dictionary where the phrase
appears?
