Pork substitute for Game Meat Pie I found out my friend can’t have fatty pork products (grew up not eating it for religious reasons and now if she has really rich fatty pork products it makes her sick) but she was super excited to try a Game Meat Pie I make with elk and rabbit. Unfortunately, the recipe calls for some back bacon and pork belly so that the fat keeps the leaner game meats from drying out. Does anyone know what I can maybe substitute for the back bacon and pork belly that will still give me the fat I need?
Duck fat.

You could use butter, of course, which would make it delicious like everything made with butter is.  But duck fat has a higher melting point than butter and in that respect is more like lard.  Duck fat is super delicious.  Also it seems to me duck fat is more in accord with the overall ethos of a game meat pie.

You could buy plain duck fat.  Or you could first have your friend over for roast duck, and you would then save the rendered fat and have her over for the game meat pie later.  Do the duck in a way such that any flavor in the fat will match what you intend with the game meat pie - for example duck with Moroccan spices would be great but those spices might then crash the game meat pie party.
