What is eel sauce?

Eel sauce, also called nitsume, unagi or kabayaki sauce, is the glaze commonly used on unagi (freshwater eel) in Japanese cooking. Despite the name, the sauce itself is not made from eel — it’s a savory-sweet reduction used to finish grilled fish and other dishes. This homemade version uses readily available ingredients and delivers the same sticky, glossy flavor you expect from store-bought unagi sauce.

Does this unagi sauce taste fishy?

No — the sauce does not taste fishy. The name refers to its association with eel dishes, not its ingredients. Its flavor is a concentrated mix of soy-forward saltiness, gentle sweetness and umami, which complements many foods such as:

• Sushi (especially the eel roll)
• Beef and chicken
• Grilled vegetables
• Japanese tempura

What type of rice vinegar should I use?

Use seasoned rice vinegar (sometimes labeled as rice cooking wine or rice wine vinegar). It provides a mild sweetness and acidity similar to mirin and helps mimic traditional unagi sauce flavors without requiring specialty ingredients.

What type of white wine should I use?

If you don’t have mirin or sake, a dry white wine works well. Chardonnay, Pinot Grigio or Sauvignon Blanc are all suitable. Choose a wine you’d be happy to drink — the wine’s flavor concentrates as the sauce reduces.

How to make this recipe

Ingredients

• 1/8 cup seasoned rice vinegar
• 1/8 cup dry white wine (Chardonnay, Pinot Grigio or Sauvignon Blanc)
• 1/4 cup soy sauce (low sodium or regular)

Instructions

• Combine all ingredients in a small saucepan and bring to a gentle boil over medium heat.
• Reduce heat slightly and simmer, stirring every 30 seconds, for 4–6 minutes until the liquid reduces and begins to thicken.
• Keep stirring as it thickens to prevent burning. Remove from heat once the sauce coats the back of a spoon and has a glossy consistency.
• Transfer to a heat-safe container and let cool. The sauce will thicken further as it cools. Yield is approximately 1/4 cup.
