Bauernfrühstück (German Farmer's Breakfast) vs Classic Fish Pie

Both dishes are starch-heavy and built on potato, onion, butter, egg and parsley, yet they treat them in opposite ways. The Bauernfrühstück fries cubed potatoes in rendered bacon fat until golden and crisp, softens the onion to slight caramelization, then sets whisked eggs over everything in the skillet, finishing with fresh parsley. The fish pie boils its potatoes into a smooth, buttery mash spread over a creamy roux sauce of milk-poached smoked haddock and white fish, scented with bay, dill and leek, with hard-boiled eggs folded in. One is crisp and smoky, the other soft, creamy and gently aromatic.
