Koreha (Rapa Nui Grilled Eel)

Ingredients

Equipment Needed

• •Charcoal grill or sturdy gas grill
• •Dry grill-safe volcanic cooking stones or a heavy cast-iron griddle
• •Fish basket or wide metal spatula
• •Instant-read thermometer

Instructions

1. 1

   Choose the koreha

   Buy the eel cleaned from a fishmonger who can tell you when it came out of the water. It should smell clean, like the sea and almost nothing else. Rinse away any blood, pat it very dry, and cut it into sturdy sections or fillets that will hold together over the fire.

   Eel is not a raw-fish food. Cook it fully, because raw eel blood can irritate and make people sick. The finished flesh should be opaque, flaky, and at least 145F in the thickest part.
2. 2

   Salt and score

   Score the skin lightly every inch so it doesn't curl hard on the grill. Salt the koreha all over and let it sit 15 to 20 minutes while the fire comes up. Pat away the moisture that rises, then rub the eel with the oil. Keep it plain. The old work here is fish, salt, stone, and patience.

3. 3

   Heat the stones

   Build a medium-hot charcoal fire, or heat a gas grill with a heavy cast-iron griddle. If you use cooking stones, use only dry, grill-safe volcanic stones set over the heat until they are fierce enough that your hand can stay a few inches above them for only two seconds.

   Never use wet river stones or unknown stones in a fire. They can crack hard when heated. A cast-iron plancha is the honest home stand-in when you don't have the right stones.
4. 4

   Grill skin first

   Lay the eel skin side down on the oiled grate, stone, or griddle. Let it sit without fussing until the skin tightens, crisps at the edges, and releases cleanly, about 4 to 6 minutes. Eel carries its own fat, so watch for flare-ups and move the pieces to calmer heat if the fire gets too hungry.

5. 5

   Turn and finish

   Turn the koreha and cook the flesh side until it is opaque and glossy, another 3 to 6 minutes depending on thickness. The flesh should flake when pressed, but not dry out. No blame the eel if it turns tough. That means the fire ran too hot or you kept it on too long.

6. 6

   Rest and share

   Move the eel to banana leaf and let it rest 5 minutes so the juices settle back in. Finish with a small pinch of sea salt and lime or lemon if you want that modern bright edge. Serve it family-style with roasted kumara or taro beside it, enough for one more hand to reach in.

Chef Tips

• •Sourcing first. If your fishmonger can't tell you when the eel was cleaned, keep walking. Fresh eel should be firm, glossy, and clean-smelling, never sour or muddy.
• •No koreha where you live? Conger eel or farmed freshwater eel will cook well this way. If you use mackerel or another oily fish, it will still feed you, but call it grilled fish, not koreha.
• •The old Rapa Nui image is hot stone and shore fire. In a home kitchen, a cast-iron griddle on a grill is better than pretending with unsafe stones. Keeper, not showman.
• •Serve it with kumara, taro, rice, or whatever is on your table. Rapa Nui kept old foods alive, and the islands also eat what the week gives them. Eat what you have.

Advance Preparation

• •Ask the fishmonger to clean the eel the day you plan to cook, or no more than 24 hours ahead. Keep it very cold and uncovered on a rack in the fridge so the skin dries.
• •Roast the kumara or taro earlier in the day and warm it gently before serving.
• •Salt the eel only 15 to 20 minutes before grilling. Overnight salting pulls too much moisture and changes the texture.
