I don’t get it either. When I was a small child my grand parents would do fried chicken, hamburgers, watermelon and homemade ice cream I would take turns cranking the maker.
But that was a long time ago when watermelons actally had seeds
Many good memories of cranking homemade ice cream and watermelon seed-spitting on my grandparents porch
The rural churches where I grew up would have ice cream socials scattered through the summer, and us kids taking shifts at cranking.
