This Unagi Sauce is perfect for homemade sushi rolls and bowls. It’s sweet, savory, and full of umami flavor, with a thick, syrupy texture that’s just delicious.
Once the sugar is dissolved and it’s boiling, bring the heat down to low and let it simmer for 8-10 minutes, or until the sauce begins to thicken. Remove from the heat immediately. It will continue to thicken as it cools. Serve chilled.
