Ingredients
- 1 cup Ice water
- ¾ cup All-purpose flour
- ¼ cup Cornstarch
- 2 quarts Vegetable oil for frying
- 1 medium Zucchini
- 1 large Bell pepper, any color
- 4 whole Shiitake mushrooms
- 1 small Sweet potato
- ½ cup Dashi broth or warm water
- 3 tablespoons Soy sauce
- 1 tablespoon Mirin or honey
- ½ teaspoon Fresh ginger, minced
Instructions
- 1
Cut the zucchini lengthwise into 3-inch-long, 0.25-inch-thick strips by laying it on the cutting board and slicing parallel to the long edge, creating flat planks, then cutting those planks into strips.
- 2
Cut the bell pepper in half lengthwise from top to bottom, remove the seeds, then cut each half crosswise into 1.5-inch-wide strips so you have rectangular pieces.
- 3
Place each mushroom cap stem-side down on the cutting board and slice straight down through the cap into 0.5-inch-thick slices, leaving the stem end attached so slices stay connected.
- 4
Peel the sweet potato using a vegetable peeler by scraping away the thin brown skin, moving the peeler away from your fingers. Then cut the potato into 0.25-inch-thick rounds crosswise.
- 5
In a small bowl, whisk together the dashi, soy sauce, mirin, and minced ginger until the sugar dissolves, about 30 seconds. Set the bowl next to the stove.
- 6
Pour 1 cup of ice water into a separate small bowl — the water should be very cold so the batter stays cool and makes the tempura crispy.
- 7
Fill a deep pot or fryer with 2 quarts of vegetable oil, then heat over medium-high heat until a cooking thermometer reads 350°F, about 10 minutes. Test readiness by dropping a tiny pinch of batter into the oil — it should sizzle immediately and float.
- 8
While the oil heats, add 0.75 cup flour and 0.25 cup cornstarch to the ice water bowl, then stir with a fork just 8–10 times until barely combined — lumps are okay, because smooth batter absorbs more oil and becomes heavy.
- 9
Dip a zucchini strip into the batter so all surfaces are coated but not dripping thick, then carefully lower it into the hot oil by laying it away from your body.
- 10
Fry 4–5 pieces of vegetables at a time for 2–3 minutes, turning once halfway through with tongs, until the surface is pale golden and crispy, like light honey in color.
- 11
Use a slotted spoon or wire skimmer to lift the cooked tempura from the oil and place it on a plate lined with paper towels to drain excess oil.
- 12
Repeat steps 9–11 with the remaining vegetables until all pieces are fried, cooking them in the same small batches.
- 13
Arrange the hot tempura on a serving plate in a loose pile or on a bed of shredded daikon radish if you have it, leaving the center of the plate visible.
- 14
Pour the dipping sauce into two small bowls and place one on each side of the tempura plate for dipping.
