Examples: 

Regardless, let's be cautious with improvising:  If the mid-products are not flipped at mid-preparation, or if a thicker layer of dough-mix is loaded into the roastpan, or if we slip to a full-tray filling or overfilling practice, we are technologically approaching the concocting of a distantly associated but distinctive dish - we may end up with a traditional potato baba (aka knolltorte / harulla / placerka).  (Source: J∙ Okram - Bartonian Potato Pancakes  ●  Cooking Recipe.)
