Pop-open Cruller (开口笑)

开口笑 · kāi kǒu xiào

家庭快手版 · Home version: 家庭版:油炸小球,咬开会心一笑

These golden balls crack open when bitten, revealing a hollow center — hence the name 'laughing opening.' A Sichuan festival treat, crispy outside, chewy inside, rolled in sugar.

Instructions

  1. 1Mix糯米粉, sugar, lard and warm water. Knead into smooth dough. Rest 15 minutes.

    🔍 Look for

    Visual: 面团应柔软可塑,如橡皮泥Dough should be soft and pliable, like playdough

    You know it's right when: 面团光滑不裂

  2. 2Form into 15 small balls (about 25g each). Roll each in water, then sesame seeds.

    🔍 Look for

    Visual: 芝麻应粘牢——若脱落说明面团太干Sesame should adhere well — if falling off, dough is too dry

    You know it's right when: 芝麻覆盖均匀

  3. 3Heat oil to 160°C (320°F). Fry balls, stirring gently, for 8-10 minutes.

    🔍 Look for Medium heat 约8-10分钟

    Visual: 球应浮起并缓慢膨胀——裂纹会出现Balls should float and slowly expand — cracks will appear

    You know it's right when: 浮起、表面微裂

  4. 4Increase heat to 180°C for 1 minute to crisp. Drain on paper towel.

    🔍 Look for

    Visual: 颜色应深金黄——不浅(欠炸)不深(过炸)Color should be deep golden — not pale (under) or dark (over)

    You know it's right when: 金黄酥脆

  5. 5While hot, toss in extra sugar if desired. Cool and serve.

    🔍 Look for

    Visual: 咬下应裂开露出空心Finished product should crack open when bitten, revealing hollow center

    You know it's right when: 咬开'开口笑'

Tips

  • · Oil temperature is critical — too hot outside burns before inside cooks
  • · The cracks forming are the signature — don't try to prevent them
  • · Fry in batches — overcrowding drops oil temp
  • · Best eaten same day — they lose crispiness overnight

Common questions

I can't find Sichuan peppercorns. What do I use?

Honestly, there is no true substitute — the numbing (má) sensation is unique. Best local approximation: 1/2 tsp black pepper + a little citrus zest for warmth and brightness. If you cook Sichuan food regularly, buy them online; they keep for months in an airtight jar.
