what are sinkers? idk.. my family been making them for a long time. it is basically a dumpling .only heavier. it is called a sinker for 2 reasons. 1: they sink to the bottom of the pot when cooking and 2 they are heavy and sink to the bottom of your belly. :) they have no actual flavor. they are a great filler. the gravy is what gives them their awesomness. They also are great in soups. With mushroom gravy, pan gravy, white gravy, peppered gravy, sausage gravy, well any kind of gravy really! :)
