- 2 tablespoons mirin (sweet rice wine)
- ¼ teaspoon salt
- 8 count large shrimp, peeled and deveined

- ¾ cup all-purpose flour
- ¼ cup cornstarch
- ¾ cup ice water

- ¼ sheet nori (seaweed sheets)
- 1 pinch shichimi togarashi (seven spice blend)
Instructions
- 1
Prepare your tempura ingredients. Pat 8 large shrimp completely dry with paper towels and set on a plate — dry shrimp will fry crispier. Clean 4 shiitake mushrooms by wiping with a damp towel, then remove the stems and slice the caps in half. Peel 0.5 medium Japanese sweet potato and slice into 1/8-inch-thick rounds — keeping them thin ensures they'll be tender inside while staying crispy outside.

Set up your tempura batter station. In a medium bowl, whisk together 0.75 cup all-purpose flour and 0.25 cup cornstarch. In another bowl, combine 0.75 cup ice water (use water straight from the fridge) with 1 large egg yolk and whisk just until combined — do not overmix. The batter should be lumpy and thin, like thin pancake batter. Lumps make for crispier tempura.

Prepare your broth. Pour 4 cups dashi stock into a medium saucepan and bring to a simmer over medium heat — you should see gentle bubbles breaking the surface, not a rolling boil. Stir in 3 tablespoons low-sodium soy sauce, 2 tablespoons mirin, and 0.25 teaspoon salt. Taste and adjust — the broth should be savory and lightly sweet. Keep it at a gentle simmer while you fry the tempura.
- 4
Slice 2 green onions on a sharp bias into 1-inch pieces and set aside. Nori will be used for garnish at the end.
- 5
Heat 3 cups vegetable oil in a heavy-bottomed 4-quart pot over medium-high heat. The oil should reach 350°F on an instant-read thermometer — this takes about 8-10 minutes. A small piece of batter should sizzle immediately and float to the surface within a few seconds. Do not let the oil smoke or exceed 365°F, or the outside will burn before the inside cooks through.
- 6
Working in batches to avoid crowding, dip each shrimp into the lumpy batter, making sure it's fully coated, and gently lay into the hot oil. Fry 3-4 shrimp at a time for 2-3 minutes until they turn pale golden-brown and float to the surface — they should sound crispy when you tap them with a spoon. Use a slotted spoon to transfer to a plate lined with paper towels.
- 7
Fry the mushroom halves next. Dip into batter and fry 4-6 pieces at a time for 1.5-2 minutes, until the batter puffs and turns light golden — the mushrooms cook much faster than shrimp. Remove to the paper towel-lined plate.
- 8
Finally, fry the sweet potato slices in the same batches, about 2-3 minutes per batch, until they are deep golden and crispy. All the tempura should rest on paper towels to drain excess oil.
- 9
Bring a large pot of water to a rolling boil over high heat. Add 8 ounces fresh udon noodles and cook according to package directions, usually 2-3 minutes for fresh noodles. Stir gently once or twice to prevent sticking. Drain in a colander and rinse briefly under warm water to remove excess starch — this stops them from overcooking.
- 10
Divide the drained noodles between two large bowls. Ladle the hot dashi broth around the noodles — you want about 1.5 cups per bowl. Arrange the tempura pieces on top: 4 shrimp, 2 mushroom halves, and 3-4 sweet potato slices per bowl.
- 11
Garnish each bowl with 1 stalk of sliced green onion scattered over the top. Tear a quarter of the nori sheet into small strips and sprinkle across the surface. Add a pinch of shichimi togarashi for a hint of heat and complexity.
- 12
Serve immediately, while the tempura is still crispy and the broth is steaming. The contrast of crispy tempura against silky noodles and hot broth is the soul of this dish — don't let it sit, or the tempura will soften.
