Headnote
This is tempura in its purest form: light, dry, and sharply defined, with each vegetable cooked to preserve its own character. The batter should form a delicate shell rather than a coating, and the oil must be managed with discipline so the result remains clean, brittle, and elegant. Served immediately, it offers contrast in texture and a quiet, exacting balance of sweetness, earthiness, and freshness.

Ingredients

Vegetables

Lotus root, peeled and sliced into 40 g

Sweet potato, peeled and cut into thin batons, 35 g

Asparagus, trimmed, 30 g

Green bean, trimmed, 20 g

Enoki mushroom, trimmed and separated, 15 g

Tempura batter

Wheat flour, 30 g

Egg, beaten, 25 g

Water, ice-cold, 35 g

Salt, 1 g

For frying

Vegetable oil, 500 g

Method

1. Prepare the vegetables with precision. Slice the lotus root evenly so it fries at the same rate throughout. Cut the sweet potato into thin, uniform batons. Keep the asparagus and green bean trimmed to neat lengths, and separate the enoki into small clusters. Pat all vegetables completely dry; surface moisture will weaken the batter and disturb the crust.

2. Make the batter just before frying. Combine the wheat flour and salt in a bowl. Add the beaten egg and ice-cold water, then stir briefly with chopsticks or a whisk only until the mixture is loosely combined. Small lumps are desirable. The batter should remain pale, fluid, and lightly textured, not smooth or elastic.

3. Heat the oil to 170°C. Maintain the temperature steadily; if it falls too far, the coating will absorb oil, and if it rises too high, the batter will color before the vegetables are properly cooked.

4. Dip the vegetables in the batter in the order listed. Coat each piece lightly and allow excess batter to drip away. Fry in small batches for 2 to 4 minutes, turning once if needed, until the coating is crisp, pale gold, and delicately ridged. The lotus root and sweet potato should be tender at the center; the asparagus, green bean, and enoki should remain vibrant and just cooked.

5. Lift the tempura from the oil and drain immediately on a wire rack set over paper. Season at once with the salt, using it sparingly so the crust remains clean and dry. Serve without delay while the batter is still brittle and the vegetables retain their contrast.

Plating and serving
Arrange the tempura in a restrained cluster, with the larger pieces set first and the lighter mushrooms and beans placed to finish the composition. Keep the plate open and balanced, allowing the crisp edges to remain visible. Serve immediately so the shell stays dry and the vegetables hold their distinct textures.

Professional notes
The batter must be mixed minimally and kept cold; this is the difference between tempura and fritter. Fry in controlled batches to preserve oil temperature and avoid heavy coloration. Drain on a rack, never in a closed container, so the crust remains light and audibly crisp.
