🔄 Ingredient Substitutes & Tips
| Original Ingredient | Recommended Substitute | Characteristics & Tips |
|---|---|---|
| Seasoned seaweed flakes | Crushed regular seasoned seaweed sheets | Use a 1:1 ratio. Slightly less crispy, but virtually identical in flavor. |
| Toasted sesame seeds | Crushed roasted peanuts or toasted perilla seeds | Use a 1:1 ratio. Offers a similar nutty texture, but adds its own distinct aroma. |
| Canned tuna | Canned salmon or shredded cooked chicken breast | Use a 1:1 ratio. Salmon gives a richer taste, while chicken makes it much leaner. |

👨🍳 Cooking Steps
Place the canned tuna in a fine-mesh strainer and press with a spoon to thoroughly drain the oil.
In a bowl, combine the drained tuna, 3T mayonnaise, 0.5t sugar, and a pinch of black pepper, mixing well.
To 2 bowls of warm rice, add 1T sesame oil, 1T toasted sesame seeds, and 0.3t fine salt. Mix gently using a slicing motion with a spatula.
Put on plastic gloves, take half of the seasoned rice, shape it into a ball, and make a deep well in the center.
Fill the well with 1 generous tablespoon of the tuna mayo mixture. Wrap the surrounding rice over it and squeeze firmly to seal.
Spread seasoned seaweed flakes on a wide plate, then roll the shaped rice ball until it is evenly coated.
🌟 Pro Chef Tips
- • If the rice is steaming hot, the mayonnaise may melt and become oily. Let the rice cool slightly to a warm temperature before assembling.
- • For a spicy kick, finely mince half a green chili pepper (Cheongyang chili) and mix it into the tuna mayo filling.
- • Lightly coat your plastic gloves with sesame oil to prevent the rice from sticking, making shaping much easier.
⚠️ Avoid Common Pitfalls
- ❌ If the tuna is not drained thoroughly, moisture will seep out, making the rice soggy and the seaweed damp. Ensure it is pressed completely dry.
- ❌ Failing to squeeze and shape the rice ball firmly will cause it to fall apart upon the first bite.
- ❌ If you over-season the rice, combining it with salty seaweed flakes will make the dish overly salty. Keep the rice seasoning light.
🧂 Spice & Seasoning Adjustments
- • The key to the tuna mayo filling is a tiny amount of sugar and black pepper.
- • Sugar cuts through the heaviness of mayo, while pepper eliminates fishy odors.
🧊 Storage & Reheating
- • Best consumed immediately.
- • If storing for later, shape the rice balls without seaweed flakes and wrap tightly with plastic wrap.
- • Store in a cool place and roll in seaweed flakes right before serving.
❓ Frequently Asked Questions
Q. Can I make these in advance and store them in the fridge?
A. Because of the mayonnaise and rice starches, the rice will harden in the fridge. They are best enjoyed at room temperature within 3-4 hours. If necessary, keep them in an airtight container in a cool place.
Q. Can I use toppings other than seaweed flakes?
A. Yes, you can roll them in Japanese furikake, toasted sesame seeds, or fish roe (tobiko) for a unique and savory twist.
Q. How can I prevent the tuna mayo from being too greasy?
A. Thoroughly draining the tuna oil is step one. Adding 0.3t of wasabi or 1 tbsp of finely chopped pickled radish/onion adds texture and cuts greasy richness.
Q. Why do my rice balls keep falling apart?
A. If the rice is too cold or contains too much oil, it loses sturdiness. Use warm rice and squeeze firmly with both hands while shaping.
Q. How can I use leftover tuna mayo filling?
A. Spread it inside sandwich bread/rolls for a quick breakfast sandwich, or place it on top of a bowl of warm rice for a quick Tuna Mayo Deopbap.
