I just listened to a food journalist prattle about quince paste, and she lives in New York. She talked about buying pineapple quinces for a tasty paste, then learning about quinces from a Japanese shrub of some kind. I don't know about either of those.
I know about the quince tree in my grandmother's orchard in New Mexico. It was a pale fruit, and like a peach, needed peeling, because it was fuzzy.
It was fairly pale, almost white, and was used with peaches for exquisite preserves when my grandmother preserved peaches. It created a tart-sweet preserve. It was unlike any others. People knew of it and ate it in the early 1900s/
I suspect we are going back again to more than the quince.
Our ancestors ate more widely than most of us do, because they had the water and the space to grow more fruits and vegetables.
I have read today about the "Paleo diet" and don't think much of it. That is too far back. Whatever type of hominids then didn't live long.
Unless you are going to be harvesting (swinging the scythe) all day long or cutting trees, or digging canals, you don't need the amount of meat most restaurants offer, nor the carbs, etc. Actually, the diabetic diet, so-called. suits most of us: meat the size of your palm, carbs: half that size, and green-yellow veggies plus salad the size of the whole hand.
I never ate pasta growing up and don't know how to balance it against other foods. People who eat pasta regularly don't eat corn tortillas, and vice versa.
I eat tortillas.
My late mother-in-law loved persimmons, which had to be ripe and frozen in the first frost or in the freezer. She would be diving into one today.
I grew up eating pomegranate seeds, but it never occurred to me to squeeze all the juice out. Not a bad idea and still a tradition.
On the other hand, I never ate mangos or papayas until I was grown.
We are clinging to our local plants, and reaching for our exotic or forgot foods.
Seems like a tasty food basket to me.
