The author tasted this snack years ago, asked around for the rough recipe, and failed to recreate it until a flash of inspiration finally made it work this year. The result is shatteringly crisp — exactly the flavor remembered. The key is using low-starch, non-mealy sweet potatoes with more moisture.

Steps

  1. Chinese New Year Crispy Sweet Potato Chips (Yulan Pian) — step 1 visual checkpoint.

    Boil a pot of sweet potatoes. Choose a variety that is moist and juicy rather than high in starch. Alternatively, peel, slice, and steam them instead.

    ✅ Done when: The sweet potatoes are fully cooked and tender all the way through.

    Step 2

    Once cooked, peel the sweet potatoes and mash them with a spatula until no lumps remain.

    ✅ Done when: The mash is completely smooth with no visible pieces or lumps.

    Step 3

    Add white sugar to the mashed sweet potato. If the sweet potatoes are naturally sweet, use less sugar — adjust to taste. Too much sugar will make the pieces stick together during frying.

    ✅ Done when: The sugar is fully mixed in and the mash tastes pleasantly sweet but not overly so.

    Step 4

    Add the glutinous rice flour. Sweet potato starch was tested, but the fried result was slightly hard; glutinous rice flour gives a crisper result.

    ✅ Done when: The flour is incorporated evenly into the sweet potato mash.

    Step 5

    Add just a little baking soda — it makes the chips lighter and crisper.

    ✅ Done when: The baking soda is evenly distributed through the mixture.

    Step 6

    Knead into a dough, slightly softer than noodle dough. Sweet potato varieties differ, so adjust the amount of flour as needed. Shape it so it holds its form.

    ✅ Done when: The dough holds together and keeps its shape when formed.

  7. 7

    Step 7

    Chinese New Year Crispy Sweet Potato Chips (Yulan Pian) — step 7 visual checkpoint.

    Shape the dough into logs, like rice cake (nian gao) sticks.

    ✅ Done when: The dough is formed into even, uniform logs that hold their shape.

    Steam the logs (or boil them). Steam for about 20 minutes. On the first attempt they were boiled for 20 minutes, but boiling loses much of the sweetness. The logs puff up while steaming, so leave adequate space between them.

    ✅ Done when: After about 20 minutes the logs are cooked through and have puffed up.

  9. 9

    Step 9

    Chinese New Year Crispy Sweet Potato Chips (Yulan Pian) — step 9 visual checkpoint.

    ✅ Done when: The logs feel completely hard and dry to the touch.

  10. 10

    Step 10

    Chinese New Year Crispy Sweet Potato Chips (Yulan Pian) — step 10 visual checkpoint.
