I live in an area where many immigrated to in 1860 ~ from Cornwall UK to, work in an very arid / area with no fresh water for 80 kms
The main diet of many of the new ….residents was the Cornish Pasty ….it was traditionally made with the join / rolled edge on the top so miners had a “ handle to hang onto with their dirty hands to eat the pasty , which was at times made as a main meal and a desert all in one package ….so to speak ..desert one end …meat and veggies the other ( the miners would dispose of the top roll after eating the contents, as it would be to dirty to eat )
