This is a fanstastic post. So pleased that you have thought of it.
BOOKS, MAGAZINES & GOVERNMENT HISTORICAL RECIPES are the items I have been collecting since time memorial ... Since, I can read in several Latin Languages, I have quite a vast variety in Italian, Portuguese, Spanish and French as well as German and Galician ( a language very similar to Portuguese with Latin overtones ) ...
Some of my faves include:
1) 1928 - The Parador Hotel Network Hotel Recipes ( there are 93 hotels, 50 which are purpose built & modern and the rest are restored fortresses and castles, manor mansions, monasteries, convents and palaces )
2) My Mom Eva´s Cake, Bread and Cookie Recipes from a book dating back to the 1950s ... Truly a treasure to have for international cake recipes and multi ethnic holiday cookies.
3) The regional Spanish cookbooks from the Tourism Bureau of Galicia, Cantabria, Andalusia, The Castillas, The Basque Country, Catalonia, Mallorca, Asturias and the Canary Islands, Melilla and Ceuta.
They are in Spanish and they contain historical dishes of each region.
I could go on and on, however, I am not home to provide the exact titles or publishing houses.
Have great day and thanks again for posting.
