White hominey or the yellow stuff?
Not a huge hominy buff but from time-to-time buy a can and eat it raw, straight from the can. Colon quivers in anticipation of the fibrous mass due to arrive in 24 hours or so.
Also, isn't there varying sizes with some being relatively BIG while the udder type is smaller?
Don't forget chick peas. Aka cici beans and perhaps other terms. Not the same as hominy but you can mix them together and attain gustatory glee. Helps to scour out the tubes down below, I think.
Or, gorge thineself on a HUGE bowl of Grape Nuts cereal. A HUGE bowl. The abrasive action will cleanse thine innards meticulously. Just don't plan on much travelling since ye will need to inhabit the indoor outhouse for quite a spell.
