Gimbap (Seaweed Rice Rolls)

Variations

• Tuna gimbap: Add mayo-dressed tuna for a rich, savory roll.
• Cheese gimbap: Lay in a slice of cheese for a softer bite.
• Chungmu gimbap: Roll just rice, thin, served with spicy squid and radish kimchi.
• Nude gimbap: Roll inside-out so the rice is on the outside, coated in sesame.

Tips

• There is no vinegar in the rice, and that is the real difference from sushi. Gimbap rice is seasoned with sesame oil and salt. Sushi's vinegar is not only a flavour: it drops the pH and helps the rice keep, and sesame oil does nothing of the sort. So gimbap is a same-day food, and the warnings about summer picnic boxes all come from that one line. What the oil does instead is coat each grain, slowing it drying out and stopping the roll welding to itself.
• "Season it while warm" has a temperature. Cooking rice puts gimbap beside onigiri and says to cook the rice slightly wetter and shape it at around body temperature. Too hot and the steam softens the gim and the oil sits on the surface; fully cold and the starch has retrograded and the grains no longer grip each other. Oil and salt go in hot; the rolling happens lukewarm.
• Why the rice goes on the rough side. Nori is made the way paper is — a process khai phaen sets out — and the sheet comes off the screen smooth on one face and textured on the other. The rough face has more surface for the rice to key into. Spread it on the smooth side and the layer slides as you roll, and the finished roll has no sheen on the outside either.
• "Pat the fillings dry" is a rule about the gim, not the fillings. Nori is a thin polysaccharide sheet and it goes limp quickly on contact with water. Wringing the spinach and salting the cucumber is not about their own flavour; it is about how long the wrapper survives. Takuan is the same choice made another way: a pickle carries very little free water to give up.
• Wetting the knife is also about the gim. A dry blade sticks to the sheet and drags it until it tears. A film of water breaks that adhesion, and sawing rather than pressing keeps the fillings from being pushed out of the cut end.
• Season the rice while it is warm and fluffy so it holds together — wet rice tears.
• Don’t use too much rice — a thin layer over two-thirds rolls best.
• Pat the fillings dry so the roll doesn’t turn soggy.
• Brush the outside with sesame oil and wet the knife for clean slices.
