Of course we have the cookbook! See it here: https://www.vintagecookbook.com/product/plaza-cookbook-1972-first-edition/
Plaza Cookbook, 1972 First Edition: The Plaza Cookbook, written by Eve Brown, and published by Prentice-Hall, Inc., Englewood Cliffs, New Jersey, in 1972. Oversized, hard cover book with dust jacket. 340 pages. Some light hotel history (no mention of Eloise, though) plus some lavish photographs, and MANY elegant recipes, elegantly spaced and printed on heavy vanilla paper. Dust jacket has issues. Book itself is in fine condition.
At VintageCookbook.com we try to provide you with your mother’s cookbook! I know lots of current recipe bloggers write proudly that their recipes are “not from your mother’s cookbook.” We think the recipes in your mother’s cookbook provided food that was nutritious and warm and colorful and just plain yummy! We know that just looking at the cover of your mother’s Woman’s Home Companion Cook Book makes you feel good. Holding her Betty Crocker Cookbook, or her Better Homes and Gardens, or Good Housekeeping Cookbook in your hands is better than nostalgic. And cooking some of those dishes for your children will pass on a great tradition.
