Frittata with Asparagus and Scallions

This is a different sort of frittata, not the neat golden round of well-set eggs that’s probably most familiar. Here the eggs are in the skillet for barely a minute, just long enough to gather in soft, loose folds, filled with morsels of asparagus and shreds of prosciutto. In fact, when I make this frittata or the “dragged” eggs—uova strapazzate, page 143—I leave my eggs still wet and glistening so I can mop up the plate with a crust of country bread. That’s the best part of all.
