I have made Danish leverpostej, which is a wonderful and popular version of pâté. The prep was very messy and kinda gross, but it was worth the effort. The Danish version just has you put the liver, the fat, and the onions through a meat grinder several times - as many times as you like, until it's as coarsely or finely ground as you prefer. For most people that is one to three times.
I had a look at Jacques Pépins recipe and to me, it seems more like a pork meatloaf with liver than a pâté. There is four times as much ground pork as pork liver!
