Vintage 1971 cookbook, please note the year is written on the cover. I did not find any highlighting, or other writing between the covers, or on any pages. Check out page 38 “What Happened to my Bread?”. Seriously a great comedic read if not for the recipes. Page 17 reads….Set dial of Burner-with-a-Brain at about 210* F …. I can’t make this stuff up!!!
