Lotus salt lake is a striking and savory snack from Chinese cuisine, featuring lotus root slices that are crisped and coated in a salty, spicy, and slightly sweet seasoning blend. The name comes from the visual effect of the seasoned slices, which resemble a miniature salt lake. This recipe delivers a crunchy, addictive treat that is perfect for sharing or enjoying as a unique appetizer.
Ingredients
- 1 large lotus root (about 1 lb / 450 g), peeled
- 2 tablespoons (30 ml) rice vinegar
- 1 teaspoon (5 g) salt
- 4 cups (1 L) water, for boiling
- 1/2 cup (60 g) cornstarch
- 1/2 teaspoon (2.5 g) five-spice powder
- 1/2 teaspoon (2.5 g) chili powder (adjust to taste)
- 1/2 teaspoon (2.5 g) ground Sichuan peppercorns (optional)
- 1/2 teaspoon (2.5 g) sugar
- 1/2 teaspoon (2.5 g) salt, plus more for sprinkling
- Vegetable oil, for frying (about 2 cups / 500 ml)
Instructions
- Slice the lotus root into thin rounds, about 1/8-inch (3 mm) thick. As you slice, place the rounds in a bowl of water with the rice vinegar to prevent discoloration.
- Bring 4 cups of water and 1 teaspoon salt to a boil in a pot. Add the lotus root slices and blanch for 2 minutes. Drain and pat thoroughly dry with paper towels.
- In a large bowl, mix the cornstarch, five-spice powder, chili powder, Sichuan peppercorns (if using), sugar, and 1/2 teaspoon salt. Add the dried lotus root slices and toss until each slice is evenly coated. Shake off excess cornstarch.
- Heat oil in a deep pot or wok to 350°F (175°C). Working in batches, fry the lotus root slices for 2–3 minutes, until golden and crisp. Do not overcrowd the pot. Remove with a slotted spoon and drain on paper towels.
- Increase the oil temperature to 375°F (190°C). Fry the slices again in batches for 1–2 minutes, until deeply golden and very crispy. Drain again.
- Immediately sprinkle with a little extra salt while hot. Toss gently to coat. Serve warm.
Tips
- Substitutions: If lotus root is unavailable, use jicama or water chestnuts, though the texture will be slightly different. For a milder version, omit the chili powder or reduce it to 1/4 teaspoon.
- Storage: These are best eaten fresh, but you can store leftovers in an airtight container at room temperature for up to 1 day. Reheat in a toaster oven to restore crispness.
- Common mistake: Not drying the lotus root thoroughly after blanching leads to soggy coating. Pat each slice dry with a clean kitchen towel.
- Do not skip the double fry: The first fry cooks the root, the second fry creates the crunch. Skipping the second fry results in a chewy texture.
Serving Suggestions
Serve lotus salt lake as an appetizer or snack with a dipping sauce like soy sauce mixed with a little vinegar and chili oil. It also makes a great topping for salads or a crunchy garnish for noodle dishes. Pair with a cold beer or a light white wine.
Variations
- Sesame: Sprinkle with toasted sesame seeds before serving.
- Garlic: Add 1/2 teaspoon garlic powder to the seasoning mix.
- Sweet & Spicy: Increase the sugar to 1 tablespoon and add a drizzle of honey after frying.
- Baked version: Toss the coated slices with 2 tablespoons oil and bake at 425°F (220°C) for 20–25 minutes, flipping halfway, until crisp. This will not be as crunchy as frying.
Storage and Reheating
Leftover lotus salt lake can be stored in an airtight container at room temperature for up to 1 day. To reheat, place in a toaster oven or air fryer at 350°F (175°C) for 3–5 minutes until crisp. Do not microwave, as it will make them soggy. If you need to keep them longer, freeze the fried slices in a single layer, then transfer to a freezer bag for up to 1 month. Reheat directly from frozen in a 375°F (190°C) oven for 5–7 minutes.
Frequently Asked Questions
Can I use pre-cut lotus root from a package? Yes, but check the package for any preservatives and rinse well. If they are already sliced, skip the slicing step and proceed with blanching.
Why do I need to blanch the lotus root? Blanching removes some of the starch and helps the lotus root cook evenly. It also helps the coating stick better.
Can I make this gluten-free? Yes, use gluten-free cornstarch (most are) and ensure your five-spice powder is gluten-free. Check labels.
My lotus root turned brown. What went wrong? The rice vinegar in the soaking water should prevent browning. If it still browned, the slices were exposed to air for too long. Soak them immediately after slicing.
Can I use a different oil for frying? Yes, use a neutral oil with a high smoke point like canola, peanut, or sunflower oil.
Is it necessary to double fry? For the crispiest result, yes. The double fry removes excess moisture and creates a hard, crunchy shell. If you skip it, the texture will be chewier.
