Ingredients
- 200 g Red Kidney Beans (dry, rinsed)
- 200 g Broad Beans (dry, peeled if possible)
- 200 g Soybeans (dry, rinsed)
- 200 g Corn Kernels (dry, yellow corn)
- 500 g Sweet Potatoes (peeled and boiled, then mashed)
- 500 ml Water (boiling water for scalding)
- 30 g Salt (fine sea salt)
- 5 g Sichuan Pepper (ground)
- 15 g Chili Powder (mild to medium heat)
- 20 g Fresh Ginger (peeled and finely grated)
- 5 g Wild Chive Roots (optional, finely chopped)
Instructions
Grind Red Kidney Beans
Place the dry red kidney beans in the grinder and pulse until a coarse flour forms. Sift through a fine mesh sieve, discard the skins, then grind again until the flour is fine.
Time: PT15M
Grind Broad Beans, Soybeans, and Corn
Repeat the grinding, sifting and second‑grind process for the broad beans, soybeans and corn kernels, obtaining four separate fine flours.
Time: PT15M
Combine Bean Flours
In a large mixing bowl, combine the four bean flours together with the mashed sweet potatoes. Mix until evenly distributed.
Time: PT5M
Scald the Flour Mixture
Bring 500 ml of water to a rolling boil. Slowly pour the hot water over the bean‑sweet‑potato mixture while stirring with a spatula until the mixture reaches a thick, pliable dough‑like consistency.
Time: PT10M
Temperature: 100°C
Steam the Dough
Divide the dough into two equal portions, shape each into a flat block, place them in two steamer baskets, and steam over boiling water for 30 minutes until fully cooked through.
Time: PT30M
Temperature: 100°C
Ferment the Steamed Paste
Allow the steamed bean paste to cool to room temperature, then keep it in a warm, covered container for three days (72 hours) at about 20‑25 °C. The paste will develop a strong aroma and become slightly sticky.
Time: PT0S
Season the Fermented Paste
After three days, transfer the fermented paste to a clean bowl. Add salt, ground Sichuan pepper, chili powder, grated ginger, and optional wild chive roots. Mix thoroughly.
Time: PT10M
Pound the Seasoned Paste
Using a mortar and pestle or a wooden pounding board, pound the seasoned paste until it becomes uniformly smooth, glossy and slightly sticky. This may take 10‑15 minutes of steady work.
Time: PT15M
Shape into Small Patties
Divide the paste into bite‑size portions (about 5 cm diameter, 1 cm thick) and shape each into a smooth patty. Place them on a drying rack.
Time: PT10M
Dry the Patties
Allow the patties to air‑dry at room temperature for about 2‑3 hours, turning them once halfway, until the surface is no longer tacky.
Time: PT30M
Optional Pan‑Fry Before Serving
Heat a thin layer of oil in a skillet over medium heat. Fry the dried patties for 2‑3 minutes per side until golden and fragrant. Serve hot with rice or as a condiment.
Time: PT10M
Temperature: 180°C

Critical Steps — Do Not Skip
- Grinding all beans to fine flour
- Scalding the flour mixture with boiling water
- Steaming the dough blocks
- Three‑day fermentation at warm temperature
- Pounding the seasoned paste to a uniform texture
Chef Tips from the Video
- Use a clean cotton cloth to wrap the steamed blocks; it retains heat and prevents drying out during fermentation.
- Pound the paste on a wooden board with a heavy mallet for an authentic texture.
- For extra aroma, add a small handful of toasted sesame seeds after seasoning.
Troubleshooting
Paste is too dry after scalding.
Add a little more hot water (10 ml at a time) and knead until the dough reaches a pliable consistency.
Paste remains watery and does not hold shape.
Steam the dough a few minutes longer, then let it cool before fermenting; the extra cooking will bind the proteins.
Fermentation odor is weak or paste smells bland.
Ensure the fermentation environment stays warm (20‑25 °C) and keep the container loosely covered to allow gas exchange.
Patties stick together during drying.
Place parchment paper between patties or spread them out on a rack with enough space.
Storage
Refrigerator: Store dried patties in an airtight container for up to 1 month.
Freezer: Freeze patties in a zip‑lock bag for up to 6 months; thaw in the fridge before pan‑frying.
Room temperature: If kept dry, the patties can sit at room temperature for up to 2 weeks, but flavor will continue to intensify.
Make-Ahead Tips
- The fermented paste can be prepared up to three days in advance.
- Dryed patties keep well; you can make a large batch and freeze for later use.
- Seasonings can be adjusted after fermentation to suit personal heat preference.
Frequently Asked Questions
What is the cultural significance and history of Sweet Potato Bean Paste in Yunnan Chinese cuisine?
Sweet Potato Bean Paste, known locally as "甘薯豆酱," is a traditional Yunnan condiment made by fermenting a mixture of beans and sweet potato. It originated as a way to preserve legumes through winter and provides a spicy, umami boost to simple meals, reflecting the region’s love for bold, fermented flavors.
What are the traditional regional variations of Sweet Potato Bean Paste in Yunnan cuisine?
In the Kunming area the paste is often mixed with wild chive roots, while in the Dali region more chili powder is added for extra heat. Some villages substitute millet flour for part of the bean flour, giving a lighter texture.
How is Sweet Potato Bean Paste traditionally served in Yunnan households?
It is commonly pan‑fried until fragrant and served alongside steamed rice, added to hotpot broth, or used as a dipping sauce for tofu and fresh vegetables. Elderly family members often enjoy it plain, appreciating its deep fermented aroma.
During which celebrations or occasions is Sweet Potato Bean Paste typically prepared in Yunnan culture?
The paste is prepared in the autumn harvest season when sweet potatoes and beans are abundant. Families also make it for Lunar New Year gatherings as a flavorful addition to the festive spread.
What authentic ingredients are essential for Sweet Potato Bean Paste and what are acceptable substitutes?
Authentic ingredients include red kidney beans, broad beans, soybeans, corn, and sweet potatoes. If any bean is unavailable, adzuki beans or lima beans work well; corn can be replaced with white corn or hominy, and sweet potato can be swapped for pumpkin puree.
What are the most common mistakes to avoid when making Sweet Potato Bean Paste at home?
Common errors include under‑grinding the beans (leaving coarse skins), adding too much water during scalding, and fermenting at a temperature below 20 °C, which slows flavor development. Also, failing to pound the seasoned paste results in uneven flavor distribution.
Why does this Sweet Potato Bean Paste recipe use a three‑day fermentation instead of a shorter period?
A three‑day fermentation allows the natural microbes to break down the bean proteins, creating the characteristic strong aroma and sticky texture. Shorter fermentations produce a milder flavor and less depth, which is not traditional for Yunnan style.
Can I make Sweet Potato Bean Paste ahead of time and how should I store it?
Yes. After shaping and drying, store the patties in an airtight container in the refrigerator for up to one month or freeze them for up to six months. For long‑term storage, keep them in a cool, dry pantry for up to two weeks.
What texture and appearance should I look for when the Sweet Potato Bean Paste is done?
The fermented paste should be dark brown, slightly sticky, and have a glossy surface. After pounding, the mixture becomes smooth and elastic, and the shaped patties should hold their form without cracking.
What does the YouTube channel Dianxi Xiaoge specialize in?
