Understanding the Tradition and Cultural Importance of Unadon
Mastering Unadon means more than just perfecting a recipe-it’s about honoring a cherished Japanese culinary tradition that dates back to the Edo period. Unadon, or grilled eel over rice, is revered not only for its rich flavor but also for its deep cultural symbolism. historically, eel was consumed in Japan during the hot summer months, especially on Doyo no Ushi no Hi, believed to restore stamina and vitality amid sweltering heat. This beloved dish reflects a harmony of delicate techniques and bold flavors that have been passed down through generations, connecting us to centuries of Japanese heritage.
Selecting the Perfect Eel and Essential Ingredients for Authentic Flavor
Choosing premium fresh eel is the foundation of truly mastering Unadon. Opt for a medium-sized Japanese eel (unagi) with firm flesh and a glossy skin-signs of freshness and quality. Frozen eel can suffice, but thaw it slowly to preserve texture and moisture. For an authentic flavor profile, key ingredients go beyond just eel. You’ll need polished Japanese short-grain rice, which provides that characteristic sticky and tender bed for the eel to sit on. Don’t underestimate the impact of your sauce-the sweet soy-based tare is the heart of this dish, seasoning both the eel and the rice with its smoky-savory layers.
step by Step Guide to Preparing and grilling the Eel to Perfection
- Prep the eel: Rinse the eel gently under cold water and pat dry with paper towels. If using whole eel, fillet it carefully or ask your fishmonger to do so. Score the skin lightly to encourage even cooking and prevent curling.
- Steam (optional): For the classic Kanto-style Unadon, briefly steam the eel before grilling. This tenderizes the meat and reduces excess fat, resulting in a soft, melt-in-mouth texture.
- Prepare your grill: Heat a charcoal or wire mesh grill over medium-high heat until it’s hot but not smoking. Brush the grill lightly with oil to keep the eel from sticking.
- Grill the eel: Place the eel fillets skin-side down and cook for 3-4 minutes. Flip carefully using tongs, then brush with a generous layer of tare sauce. Grill for another 3-4 minutes, adding more sauce every minute to build a glossy lacquered finish.
- Rest the grilled eel: let the eel rest for 2 minutes to seal in the juices before slicing into bite-sized pieces.
Crafting the Signature Sweet Soy Sauce That defines Unadon
No element defines Unadon like the sweet soy sauce tare. This sauce balances savory soy with sweet mirin and sugar, enriched by the deep umami notes of sake and optionally, dashi. it’s a layered concoction that caramelizes beautifully on the eel,infusing each bite with signature warmth and sweetness.
- Combine 1/2 cup soy sauce, 1/4 cup mirin, 1/4 cup sake, and 3 tablespoons sugar in a small saucepan.
- Bring to a simmer over medium heat, stirring until the sugar dissolves fully.
- Reduce the heat to low, cooking gently until the sauce thickens slightly and coats the back of a spoon (about 10-15 minutes).
- Cool to room temperature before using. Store leftovers in an airtight container refrigerated for up to two weeks.

Tips for Success

- Control the grill heat: Medium-high heat ensures a crisp exterior without drying the meat.
- Layer the tare sauce carefully: Multiple thin coats produce a glossy, sticky finish rather than a burnt glaze.
- Make sauce ahead: The tare improves in flavor if made a day ahead and refrigerated.
- Steaming step: customary in eastern Japan, this step results in a delicate texture but can be omitted for a chewier style.
- Storage: Leftover grilled eel tastes great cold or reheated gently in the oven with extra sauce.
