I was always told that only a goat would eat the heel of a loaf of bread. Not sure if they meant human kids eat like goats or what. And, yeah, I've used a plunger and crock churn too. I'd rather go with the hand crank on a jar.
And, I didn't grow up on a farm. Had relatives with farms tho. Have driven a team while haying, that's with men forking the hay on the wagon by hand. Driven a team haying with men picking up hay bales by hand and putting them on the wagon, and then one or two stacking the bales, have also stacked the bales. And learned how to milk by hand. And have hand cranked more than one ice cream machine too, good stuff.
