I remember eating these since childhood. They are a popular but not-so-common-nowadays treat, less everyday only because affluence and "progress" has brought with it changing lifestyles, i.e., fewer home bakers. Anyway, it's yummy even for people like myself who don't care for nuts in baked goods. The nuts are a must in this dessert.
Just as an aside, my aunt says that she correlates eating nuts (and legumes and strawberries and cantaloupes and corn) with her arthritic fingers acting up. I tried testing it (nuts and legumes) out and it seems to hold true. Maybe try it and let us know what you find?
Just as another aside, in Australia there is a listeria outbreak tied to cantaloupes at the moment: see http://www.foodsafetynews.com/2018/03/growers-health-officials-in-high-gear-with-cantaloupe-outbreak/#.WpmEbeduiUk They've traced it to one farm there. I assume it's not a worry in the US.
