The Method
1
Soak the bread cubes in the milk for 10–15 minutes until fully saturated. Gather the soaked bread in both hands and squeeze firmly until no milk runs out. The bread should form a compact, dry mass.
2
Blanch the spinach briefly in boiling salted water, then drain. Once cool enough to handle, squeeze the spinach in successive tight fistfuls until no further moisture can be extracted; this step must be absolute. Chop the dried spinach finely.
3
Combine the squeezed bread, spinach, eggs, salt, nutmeg, and flour in a bowl. Mix until the ingredients are evenly distributed. Add flour sparingly — only as much as the mixture requires to hold a rough shape when pressed between the palm and fingers; the mass should be coherent but soft, not dough-like.
4
Shape one test dumpling into a rough oval quenelle with wetted hands — irregular in surface, not a smooth sphere. Lower it into a pan of gently simmering salted water and poach for 8–10 minutes. If it holds together and rises to the surface intact, the mixture is correctly balanced. If it disintegrates, work a little more flour into the batch; if it is dense and floury, it cannot be corrected — the minimum flour rule must be observed from the outset. This is where the dish lives or dies.
5
Shape the remaining mixture into rough oval quenelles of similar size. Lower them in batches into the gently simmering salted water — never a rolling boil, which would break the dumplings apart. Poach for 8–10 minutes; the strangolapreti are done when they float and feel set but yielding when pressed lightly with a spoon.
6
While the dumplings poach, melt the butter in a small pan over low heat. Continue heating until the milk solids turn golden-brown and the butter gives off a scent of hazelnut. Add the sage leaves in the last 30 seconds of cooking; they will crisp in the hot fat. The butter is ready when it is amber, fragrant, and the sage is rigid at the edges.
7
Remove the strangolapreti with a slotted spoon, drain briefly, and arrange on warmed plates. Pour the brown butter and sage leaves over immediately. Finish with a generous snowfall of finely grated Grana Padano or Trentino Grana and serve at once.
