Ingredients
- 8 oz lotus root (renkon), fresh
- 2 cups neutral oil (vegetable or canola), for deep frying
- ½ teaspoon salt
- ½ sheet nori seaweed sheets
- 2 tablespoons white vinegar (or rice vinegar)
- 1 cup water
- ½ tablespoon lemon juice
Instructions
- 1
Pour the water into a small bowl and add the white vinegar and lemon juice, stirring to combine. This prevents the lotus root from turning dark brown.
- 2
Scrub the lotus root under cold running water with a vegetable brush to remove any dirt, holding it under the stream for 15–20 seconds.
- 3
Using a very sharp knife or mandoline slicer, cut the lotus root crosswise (perpendicular to its length) into paper-thin rounds, about 1/16-inch thick—thin enough to see light through them.
- 4
Drop each lotus root slice into the vinegar-water mixture as you finish cutting it, so it stays submerged and doesn't discolor.
- 5
Let the slices soak in the vinegar mixture for 3 minutes, then use a slotted spoon to transfer them to a clean kitchen towel.
- 6
Pat each slice dry with the towel by laying them flat and pressing gently; moisture prevents crisping, so get them as dry as you can.
- 7
Tear the nori sheet into small pieces, about 1-inch squares, and set them aside in a small bowl.
- 8
Pour the neutral oil into a heavy-bottomed pot or deep saucepan, filling it about 2 inches deep, and attach a deep-fry thermometer to the side so the bulb is submerged but not touching the bottom.
- 9
Set the burner to medium-high heat and warm the oil until the thermometer reads 350°F; watch the bubbles rise and the surface shimmer, which takes about 5–8 minutes.
- 10
Carefully lower 4–5 lotus root slices into the hot oil using tongs or a slotted spoon, working in batches so you don't crowd the pot.
- 11
Fry the slices for 2–3 minutes, until they turn light golden brown and become translucent around the edges; use tongs to flip them halfway through cooking.
- 12
Using a slotted spoon or spider strainer, transfer the fried slices to a paper towel-lined plate to drain excess oil.
- 13
Repeat steps 10–12 with the remaining lotus root slices in batches of 4–5 until all are fried, allowing the oil temperature to return to 350°F between batches (about 1 minute between batches).
- 14
While the chips are still warm, sprinkle the salt evenly over all of them, tossing gently with your fingers to coat.
- 15
Scatter the torn nori pieces over the chips and toss once more so the seaweed adheres to the warm, oily surface.
- 16
Transfer the chips to a serving bowl or plate and serve immediately while they are still crispy and warm.
