   🕒 00:14
2. Trim the tough parts from the stems of 2 shiitake mushrooms, then thinly slice the caps and stems. [Secret Tip!] Slicing mushrooms thinly prevents them from taking too long to cook.
   🕒 00:30
3. Flake the 80g of imitation crab sticks.
   🕒 01:14
4. In a bowl, combine the sliced leek, shiitake mushrooms, and flaked imitation crab sticks.
   🕒 01:31
5. Add 1 tbsp mayonnaise and 2 tsp potato starch to the bowl and mix well to avoid clumps. [Secret Tip!] Mayonnaise helps to remove the fishy smell from the crab sticks and makes the egg fluffy. Potato starch also contributes to fluffy eggs.

6. Lightly beat 4 eggs.
   🕒 02:06
7. Pour the beaten eggs into the bowl with the other ingredients and mix thoroughly.

9. Add 300cc of water to the pot and heat over medium heat, stirring until dissolved.
   🕒 03:19
10. Add 3 tbsp vinegar and bring to a light boil to cook off the alcohol and mellow the acidity. [Secret Tip!] Skim off any scum that appears during boiling for a clear sauce.
    🕒 03:36
11. Taste and turn off the heat, then thicken the sauce with 13g of potato starch dissolved in water. [Secret Tip!] To prevent lumps when adding the starch slurry, turn off the heat before mixing.
    🕒 04:09
12. Return to medium heat and bring to a full boil to stabilize the thickening.
    🕒 04:33
13. Shape the cooked rice into your desired form and set aside.
    🕒 04:49
14. Heat a generous amount of oil in a frying pan over medium heat.
    🕒 04:55
15. Pour half of the egg mixture into the hot pan and spread it out to form a round shape.
    🕒 05:06
16. Once the surface sets and it's lightly browned, flip the omelet. Once the underside is also set, place it on top of the rice. [Secret Tip!] If flipping the omelet is difficult, slide the cooked omelet onto a plate, then place the pan upside down over it to easily transfer it.
    🕒 05:23
17. Pour the prepared sauce over the omelet. It's done!
