Steps
- 1
Season the warm rice with sesame oil, salt and sesame seeds, and let it cool to just above room temperature.
- 2
Drain the tuna and press it hard in a sieve until no more liquid comes out.
- 3
Mix the pressed tuna with mayonnaise and minced onion into a firm, scoopable filling.
- 4
Lay a sheet of gim shiny side down on a bamboo mat.
- 5
Spread rice thinly over about two-thirds of the sheet, leaving the far edge bare.
- 6
Lay the fillings in a line across the near third.
- 7
Roll away from you, pulling back on the mat each turn to tighten.
- 8
Brush the finished roll with sesame oil and slice with a wet knife.
Did you know — Korean culture
Tuna kimbap is a modern arrival, and it can be dated fairly precisely. Canned tuna only became a common Korean pantry item in the 1980s, when domestic canneries scaled up, and the tuna-and-mayonnaise roll followed quickly. It is now one of the most ordered fillings at kimbap chains, competing with fillings that are centuries older.
Canned tuna holds far more liquid than it appears to, and every drop of it will end up in the rice. Press it in a sieve until it stops dripping, then bind it with mayonnaise - the mayonnaise is structural here, not just flavour, turning loose flakes into something that stays in a line while you roll.
Tight rolling is a pulling motion, not a pushing one. After each turn, pull the mat back against the roll to compress it before continuing. A loosely rolled kimbap looks fine intact and collapses the moment the knife goes through it.
Rice goes on thinner than instinct suggests, and the far edge stays bare so it can seal. Too much rice is the second most common reason a roll splits - the filling has nowhere to go and forces the seam open.
Troubleshooting
Rolls falling apart when sliced? Rolled too loosely, and the knife needs to be wet. Pull the mat tight at every turn and wipe the blade between cuts.
Rice soggy? The tuna wasn't drained hard enough. Press it until genuinely dry.
Seam splitting? Too much rice. Spread it thinner and leave the far edge of the sheet bare.
