Found online for ZWT 7. Wikirecipes says "Pizokel were eaten in a wide variety of ways. In some places when eaten by themselves they are known in Romansh as "bizochels bluts", or “bald pizokel”. If someone leaves a small amount of any kind of food on the serving dish for politeness sake, in the Engadine this is called "far sco quel dal bizoccal", meaning more or less “leaving the last pizokel”."
