Japan-wide — integral to all nabe hotpot traditions
Shime (締め, literally 'closing' or 'tying off') is the final act of Japanese hotpot dining: using the flavour-enriched remaining broth to cook a final carbohydrate — rice (for zosui/ojiya, a savoury rice porridge), noodles (udon, ramen noodles, or thin wheat noodles), or rice directly poured into the pot (ojiya style). Shime is not an afterthought but the culmination of the meal: the broth has been continuously enriched by every protein, vegetable, and seasoning added throughout the meal, and the shime course represents the distilled essence of everything that was cooked. Different nabe have designated shime: tonkotsu shabu-shabu → zosui; mizutaki → zosui or rice porridge; sukiyaki → udon noodles; kimchi nabe → instant noodles or rice. The ritual of shime is as culturally important as the nabe itself.
The distilled essence of the entire meal — accumulated umami, fat, and seasoning absorbed into rice or noodles creates the most intensely flavoured course of the meal
Skim the broth before shime to remove oil and foam accumulated from meat and fish; adjust seasoning (the broth will have concentrated during cooking and may need dilution or additional soy); for zosui: add cooked rice to broth (not raw rice) and simmer briefly, adding beaten egg at the end for creamy binding; for noodle shime: add noodles to simmering broth and cook according to type.
The shime for shabu-shabu: beaten egg stirred through zosui at the last moment, then heat turned off and a lid placed for 30 seconds creates an egg-flower finish of exceptional delicacy; for sukiyaki udon shime: the remaining sweet warishita is already intensely flavoured — dilute with a small amount of dashi before adding udon; shime zosui may be the most satisfying single dish in Japanese cuisine — the accumulated umami of an entire meal concentrated into a small bowl of rice porridge.
Failing to skim the broth before shime (fatty, cloudy broth ruins the shime course); over-reducing the broth during the main nabe service (insufficient broth remaining for shime); using raw rice for zosui (takes too long and absorbs different amounts of liquid unpredictably); neglecting to taste and adjust broth seasoning before adding shime carbohydrate.
