STEP 2/7
It's not fishy because it's a trimming eel, but if you do it at home, you can put rice wine, minced garlic, minced ginger, and onions and marinate it for 20-30 minutes.
STEP 4/7
In the meantime, I'm going to make teriyaki sauce,
You can buy it on the market, or boil it with soy sauce, kelp water, starch syrup, ginger half, and garlic. (You can boil it with the sauce on top.). Turn it to low heat, and add some starch.)
STEP 6/7
When teriyaki sauce is made, spread the sauce on the grilled eel in a frying pan and go straight to the oven.At 250 degrees Celsius for 15 minutes ^^* (It may vary depending on the head of the eel). If you're going to put it in the oven, please take a look.)
