Sweet 'n thick, this restaurant-style eel sauce is deliciously flavorful, thanks to Japanese sweet wine, soy sauce, and sugar. This 4 ingredient recipe is so easy to make and far better than takeout! Great on shrimp, sushi, eel, and more.
Set a small saucepan over medium heat. Whisk together soy sauce, sugar, mirin, and corn starch.
Whisk occasionally, cooking until mixture has thickened and coats the back of a spoon and is semi-opaque (it won’t drip off quickly like water), about 12-19 minutes.*
Note: After about 8 minutes, I switched to low heat and continued cooking. The sauce will occasionally bubble and simmer, that’s the time to whisk--this will help reduce down the bubbles. Keep cooking until it’s somewhat thickened bearing in mind it will also thicken a bit when cooled.

Notes
*Note: I like mine thicker, so I cook it a good bit, 19 minutes. You can do 12-15 minutes for thinner sauce.
