Mix the chopped peppers with salt at a ratio of about 10% salt by weight. This helps preserve the chilies and kickstart fermentation.
Some recipes include a small amount of rice wine or baijiu to enhance fermentation. Add 1-2 tablespoons per cup of chili mixture if desired.
Combine the chili base with the prepared beans to begin the fermentation process.
The Fermentation Process
Fermenting doubanjiang transforms simple ingredients into a complex, flavorful paste through microbial activity. This process develops the characteristic savory, salty, and umami flavors that define this Chinese condiment.
Initiating Fermentation
To start fermenting doubanjiang, combine mashed soybeans or broad beans with salt, chili peppers, and wheat flour. Add a starter culture, typically Aspergillus oryzae, to kickstart the fermentation process. This mixture is then placed in a clean fermentation vessel.
Some recipes include a pre-fermented chili pepper mash for added depth. The salt content should be around 8% of the total weight to inhibit harmful bacteria while allowing beneficial microbes to thrive.
Cover the vessel with a breathable material like cheesecloth to protect the mixture while allowing air circulation.
Maintaining the Environment
Controlling the fermentation environment is crucial for successful doubanjiang production. Maintain a consistent temperature between 20-30°C (68-86°F) throughout the process.
Stir the mixture regularly to prevent mold growth and ensure even fermentation. This also helps redistribute moisture and introduces oxygen to support the fermentation process.
Monitor humidity levels to prevent excessive drying or moisture accumulation. If the mixture becomes too dry, add small amounts of water to maintain the proper consistency.
Duration and Stages of Fermentation
Doubanjiang fermentation typically lasts several months to a year, with flavors deepening over time. The process occurs in stages:
- Initial fermentation (1-2 weeks): Rapid microbial growth and breakdown of sugars
- Primary fermentation (1-3 months): Development of basic flavors and aromas
- Extended aging (3-12 months): Continued flavor development and complexity
As fermentation progresses, the mixture darkens and develops a rich, pungent aroma. The texture becomes smoother and more paste-like.
Taste the doubanjiang periodically to assess its flavor development. Once it reaches the desired taste profile, transfer it to airtight containers for storage or continued aging.
