Milan, Lombardia
Milan's ancient tripe soup — the dish that earned Milanese the nickname 'busecconi'. Honeycomb tripe slow-cooked with borlotti beans, tomatoes, celery, carrots, and sage in beef broth until collapse-tender. Finished with a shower of Parmigiano Reggiano and eaten with crusty bread. Traditionally served on Thursday evenings at Milan's old osterie.
Rich, gelatinous, deeply beefy with earthiness from the tripe and cream from melted borlotti beans — quintessential cold-weather sustenance
Tripe must be pre-boiled and changed once to remove any residual odour before the main cooking begins. The vegetables should dissolve into the broth over 2+ hours, creating a thick, homogeneous soup. The beans must be added cooked separately — they cannot withstand the same cooking time as the tripe without disintegrating. Sage (not parsley) is the canonical herb.
Blanch tripe in water with white wine vinegar for 30 minutes before the recipe begins — this removes off-flavours without boiling away the tripe's characteristic texture. A Parmesan rind added to the broth during cooking adds enormous glutamate depth. The soup is better the next day when the collagen has set the broth to a loose jelly.
Under-cooking the tripe — it must be fully gelatinous, not chewy. Omitting the bean component makes it tripe soup, not busecca. Adding the Parmigiano too early causes it to clump. Using canned tripe that has already been over-cooked produces a characterless result.
