of my Home is a definite Dunker..A favorite late evening activity/snack is a stack of whatever cookies we happen to have around...a Large glass of cold milk and her current reading material. We don't do Doughnuts often, but when we do it is a coffee dunk for her and a milk on the side for me. I Don't Dunk that stuff.
We have farm-family style restuarant in the area that serves "Fried Biscuits" and Apple Butter
... I do like to make a large puddle of homemade Apple Butter
on the bread plate and dip my Biscuit (like a raised doughnut(no hole) but not the extra sweet dough)
However, Shrimp into cocktail sauce.."Dry BBQ" into a cup of sauce,ears of corn into a bowl of melted butter, catfish fillet (finger food for me) into the tartar sauce...etc etc
I am not sure that "Dipping" and "Dunking" are the same thing.
