Grilled Eel Sandwich with Sweet Soy Glaze

Unagi (freshwater eel) is a luxury staple of Japanese cuisine, traditionally served over rice (Unadon). This recipe is a bold fusion: the rich, fatty, smoky eel is contrasted by the crisp texture of toast and the piquancy of wasabi. The caramelized flavor of the 'kabayaki' style sweet-savory sauce and the freshness of cilantro create a flavor bomb, proving that a sandwich can indeed be a gourmet dish.

Instructions

1

Combine sauce ingredients: soy sauce, mirin, rice vinegar, sugar, and half of the wasabi. Stir until the sugar dissolves.

Tip: Wasabi's heat is volatile, so mix the sauce cold; do not cook it.
2

Heat a skillet over medium heat. Place unagi fillets in the pan (skin-side down if applicable) and cook for 2-3 minutes until the fat sizzles and the edges caramelize.

Tip: There is a lot of fat under the eel's skin; rendering this fat concentrates the flavor and improves the texture.
3

Remove the eel. In the remaining flavorful fat (or a clean pan), toast the bread slices on both sides until golden brown.

Tip: Crispy bread provides essential textural contrast to the soft, rich fish.
4

Spread the remaining wasabi (to taste) and the prepared sauce on the inside of the toasted bread.

Tip: The sauce soaking into the bread pores ensures a burst of flavor in every bite.
5

Place the eel on the bread, top with fresh cilantro, and cover with the other slice of bread. Cut in half diagonally.

Tip: Serve immediately while the bread is crispy and the fish is hot.
