These triangular rice balls use canned tuna to offer three delicious flavors, from a creamy salad filling to spicy gochujang and tangy kimchi.

Steps

This is a preparation I also love to use as a tuna salad topping.
Squeeze the liquid thoroughly from the canned tuna.
Mince the cucumber and onion, then lightly pickle them in salt.
The pickled onion cuts through the richness of the tuna. Pickles are wonderful here if you have them.
You can omit the imitation crab meat.

This is often called spicy tuna. Add minced chili pepper and minced bell pepper,
then mix with gochujang (Korean red chili paste) and a little mayonnaise.
Personally, this seasoning is my favorite.

This is the kimchi tuna.
I prepared it by lightly stir-frying a little aged sour kimchi and canned tuna with a bit of sugar.
Adjust the amount of sugar depending on how sour your kimchi is.

Cut the dried seaweed sheets (gim) in half.
The size of the rice ball mold happens to match roughly half a sheet of seaweed.
Adjust and cut the size of the seaweed to match the triangle mold you have.

Cook the rice slightly firm and season with a little salt and toasted sesame oil.
I also sprinkled in toasted sesame seeds.

Spread rice into the triangle mold and add the filling in the center.

Cover with more rice, put the lid on, and press down gently to shape.

Place the shaped rice onto the seaweed, leaving a small margin at the top edge.

Wrap the bottom portion of the seaweed up over the rice,
pressing gently as you shape it so the seaweed sticks firmly to the rice.
Seal the final edge with a dab of water.
