Trentino, Trentino-Alto Adige
Trentino's recycled polenta soup: leftover cold polenta broken into chunks and added to simmering beef or pork broth with borlotti beans, lard, onion, and black pepper — the polenta dissolves partially to thicken the broth while retaining some chunks, creating a thick, porridge-like soup of remarkable depth. The name 'ribòl' comes from 'reboiled' — it is, at its most fundamental, leftover polenta reboiled in the next morning's broth. One of the quintessential re-use dishes of alpine mountain cooking.
Thick, starchy from dissolving polenta, beefy from the bone broth, with earthy borlotti beans — hearty mountain breakfast-soup of complete simplicity
Old polenta (at least 24 hours) is essential — fresh polenta dissolves too fast and creates a gluey mass rather than the desired chunky-smooth texture. The broth must be good (real bone broth, not stock cubes) — the polenta thickens it further and any weakness in the base is amplified. Lard provides the essential animal fat that makes this a sustaining mountain breakfast. The beans add both protein and texture contrast against the dissolving polenta.
Ribòl is traditionally breakfast food — the mountain farmer's warming start to a cold morning. For modern service: finish with a drizzle of raw olive oil and grated Grana Trentino. A fried egg dropped on top transforms ribòl from soup to a complete meal. The dish can be made richer by using the concentrated broth from a previous bollito misto.
Using fresh polenta — it disintegrates immediately instead of providing texture contrast. Thin broth — the polenta thickens it further but cannot add flavour depth absent from the beginning. Not cooking long enough — the polenta chunks need 20-25 minutes to soften and partially dissolve into the broth. Under-seasoning — both the polenta and the soup need generous salt.
