No parts of Draugr are used in the creation of Blood Pudding (Blood Bag [Leech], Thistle [forage], Barley Flour [farm/refinement]). PakaNoHida must be thinking of Sausage, which actually uses the Entrails dropped by Draugr.

Sausages are awesome health-oriented food for their easy ingredients and decent stats. Once you can start making them, you'll probably eat them up until the Yagluth fight.
