Harumaki-japanese Springrolls Recipe

Make the dipping sauce

In a small bowl combine 1/2 cup soy sauce, 1 tablespoon mirin, 1 tablespoon rice vinegar, 1 teaspoon sugar and 1/2 teaspoon sesame oil. Stir until sugar dissolves. Add toasted sesame seeds and chili oil or a pinch of shichimi togarashi if using. Taste and adjust: add a little more rice vinegar for acidity, or a touch more sugar for balance. Set aside at room temperature.

Prepare wrappers: If using refrigerated spring roll (wheat) wrappers, keep them covered with a damp towel while working to prevent drying. If using rice paper, have a shallow dish of warm water ready to briefly soften each sheet before filling.

Heat oil for frying: Pour about 1 cup neutral oil into a deep skillet or Dutch oven to a depth of about 1 inch (enough for shallow to medium deep frying). Heat over medium-high until oil reaches 175–180°C (350–360°F) or until a small piece of bread sizzles and browns in 30–40 seconds. Maintain temperature between 170–180°C (340–360°F) while frying.

Prepare vegetables and aromatics

Thinly shred the cabbage, julienne or grate the carrot, finely chop the shiitake, and thinly slice scallions separating whites from greens. Mince garlic and ginger. If using dried shiitake, rehydrate in warm water, reserve soaking liquid and chop mushrooms finely.

Cook the filling

Heat 1 tablespoon vegetable oil in a large skillet or wok over medium-high heat. Add the white parts of the scallions and cook 30 seconds until fragrant. Add minced garlic and ginger and stir 20–30 seconds until aromatic but not browned. Add ground pork and break up with a spatula; cook until no longer pink, about 4–5 minutes. Add chopped shiitake mushrooms and cook 1–2 minutes to release moisture. Stir in shredded cabbage and carrot and cook 2–3 minutes until vegetables begin to wilt but still retain some texture.

Season and bind

To the cooked mixture add 2 tablespoons light soy sauce, 1 tablespoon sake (or sherry), 1/2 teaspoon sugar, 1/4 teaspoon white pepper and 2 tablespoons reserved shiitake soaking liquid (or low-sodium chicken stock). Sprinkle 1 tablespoon potato starch (or cornstarch) over the mixture and stir well to combine; the starch will absorb liquid and help bind the filling. Taste and adjust seasoning — add a pinch more salt or soy if needed. Remove from heat and let cool slightly for 10 minutes.

Stir in scallion greens: After the filling has cooled a touch (so it won’t melt the wrapper), stir in the sliced green parts of the scallions. If the filling is very wet, squeeze gently in a sieve or pan-lift to drain off excess liquid before wrapping; the filling should be moist but not soupy.

Prepare egg wash

Crack 1 egg into a small bowl and beat lightly with a fork. This egg will be used to seal the wrapper edges. Keep it near your work station.

Mix in binder: If the cooked filling seems loose, you may fold in an additional 1 teaspoon cornstarch dissolved in 1 teaspoon water while still warm to help set the mixture as it cools. Ensure binder is well incorporated before filling wrappers.

Assemble the spring rolls

Work on a clean board or plate with wrappers covered by a damp towel. Place one wrapper in diamond orientation (corner toward you). Spoon about 2 tablespoons of filling onto the lower third of the wrapper, leaving a 1/2-inch border at the sides. Fold the bottom corner up over the filling, then fold both side corners in snugly. Brush the top corner edge with beaten egg and roll tightly to seal. Repeat with remaining wrappers and filling. You should get about 12 medium rolls; adjust filling amount to make smaller or larger rolls.

Fry the rolls

Carefully place 3–4 rolls into the hot oil seam-side down, do not overcrowd. Fry, turning occasionally, until evenly golden and crisp, about 2.5–3.5 minutes per batch depending on size and oil temperature. Use a slotted spoon to transfer to a paper towel-lined rack to drain. Keep finished rolls warm in a low oven (90–100°C / 200°F) if frying in batches.

Alternative: bake for a lighter version: Preheat oven to 200°C (400°F). Place assembled rolls seam-side down on a parchment-lined baking sheet, brush lightly with oil, and bake 12–16 minutes, turning once halfway, until golden and crisp.

Plate the harumaki with the dipping sauce. Garnish with shredded nori or microgreens and serve with lemon or lime wedges for a bright finish. Offer extra chili oil or soy for guests to adjust seasoning.

Storage: Cooked rolls keep in the refrigerator for up to 2 days; reheat in a 180°C (350°F) oven for 8–10 minutes to re-crisp. Uncooked assembled rolls can be frozen on a sheet tray until firm, then transferred to a freezer bag; fry from frozen adding 1–2 minutes to frying time.
