pappification

noun

Plural:   pappifications

Turning something into a mushy, pap-like substance;  especially:  softening and disintegration of overcooked or poorly designed food.

Examples: 

There are huge inter-variety differences in the potato lineage.  In pulpy cookouts (e.g., coulis, puree), the strain-specific uniquities are scarcely noticeable.  Contrastingly, with Barton-design pancakes, the unequal processing characteristics will magnify - mainly the pappification-proneness of class-C potatoes will be unmissable.  (Source: J∙ Okram - Bartonian Potato Pancakes  ●  Cooking Recipe.)
