📝 About This Recipe

A refreshing and iconic Sichuan street food, Liangfen is a translucent, jiggly jelly made from pure mung bean starch. Its neutral flavor and cooling texture provide the perfect canvas for a bold, numbing, and spicy sauce rich with chili oil and toasted aromatics. This dish is a masterclass in contrast, balancing the slippery, chilled jelly with the intense heat and crunch of its savory toppings.

🥗 Ingredients

The Jelly Base

  • 1 cup Mung bean starch (Ensure it is pure starch, not flour)
  • 6 cups Water (Divided into 1 cup and 5 cups)
  • 1/2 teaspoon Sea salt
  • 1/2 teaspoon Vegetable oil (For greasing the mold)

The Spicy Vinaigrette

  • 3 tablespoons Light soy sauce
  • 2 tablespoons Chinkiang black vinegar (Adds a complex, smoky acidity)
  • 3 tablespoons Chili oil with flakes (Adjust to heat preference)
  • 4 cloves Garlic (Finely minced)
  • 1 tablespoon Toasted sesame oil
  • 1 teaspoon Sugar (To balance the acidity)
  • 1/2 teaspoon Sichuan peppercorn powder (Freshly toasted and ground for best numbing effect)

Garnish & Texture

  • 1/2 large Cucumber (Julienned into matchsticks)
  • 2 tablespoons Roasted peanuts (Crushed)
  • 2 stalks Scallions (Finely sliced)
  • 1/4 cup Fresh cilantro (Roughly chopped)
  • 1 teaspoon Toasted sesame seeds

👨‍🍳 Instructions

  1. 1

    Lightly grease a 1-quart rectangular glass or ceramic container with a tiny bit of vegetable oil to prevent sticking.

  2. 2

    In a medium bowl, whisk together 1 cup of mung bean starch with 1 cup of room-temperature water until completely smooth and no lumps remain.

  3. 3

    In a heavy-bottomed pot, bring the remaining 5 cups of water and the salt to a gentle boil over medium-high heat.

  4. 4

    Reduce the heat to low. Give the starch slurry a quick stir (as it settles fast), then slowly pour it into the boiling water while whisking constantly.

  5. 5

    Switch to a wooden spoon and stir continuously in one direction. The mixture will quickly turn from milky white to translucent and thick.

  6. 6

    Continue cooking and stirring on low heat for 5-7 minutes. The mixture should look like a thick, glossy, and heavy gel that coats the spoon.

  7. 7

    Immediately pour the hot mixture into your prepared container. Use a spatula to smooth the surface as much as possible.

  8. 8

    Let the jelly cool on the counter to room temperature for about 1 hour. It will begin to firm up.

  9. 9

    Cover the container and refrigerate for at least 3-4 hours, or overnight, until it is cold and completely set into a bouncy block.

  10. 10

    Prepare the sauce by whisking together the soy sauce, black vinegar, chili oil, minced garlic, sesame oil, sugar, and Sichuan peppercorn powder in a small bowl.

  11. 11

    Once set, run a knife around the edges of the container and invert the jelly onto a clean cutting board.

  12. 12

    Slice the jelly into long, thin strips (about 1/4 inch thick) or into bite-sized cubes. Wipe your knife with a damp cloth between cuts if it sticks.

  13. 13

    Place the julienned cucumber at the bottom of a shallow serving bowl to act as a bed.

  14. 14

    Arrange the jelly strips over the cucumber and pour the spicy vinaigrette generously over the top.

  15. 15

    Garnish with crushed peanuts, scallions, cilantro, and sesame seeds. Serve immediately while chilled.

💡 Chef's Tips

Always use 'Mung Bean Starch' and not flour; flour contains protein and fiber which will make the jelly opaque and crumbly rather than translucent and bouncy. Constant stirring is essential during the thickening phase to ensure a perfectly smooth texture without any lumps. Do not skip the chilling time; the jelly needs to be cold to maintain its structural integrity when sliced and to provide that signature refreshing mouthfeel. If you have a traditional liangfen scraper (a metal disc with holes), use it to create long, uniform noodle-like strands for a professional presentation.

🍽️ Serving Suggestions

Pair with a cold, crisp Tsingtao beer or a sparkling jasmine tea to balance the Sichuan heat. Serve as a starter for a spicy Sichuan hot pot or alongside Mapo Tofu for a themed dinner. Accompany with a side of steamed baozi (pork buns) to turn this light appetizer into a full meal. Offer extra black vinegar and chili oil at the table so guests can customize the tang and spice levels to their liking.
