Answer Raw materials (can produce 70 kilograms of finished product):

22 kilograms of beans (also called broad beans), 53 kilograms of fresh peppers, 5.5 kilograms of flour, 12 kilograms of salt

Method:

1. Wash the beans, remove the shells, boil them in boiling water for one minute, take them out and put them in cold water to cool down, remove the debris, soak them for three to four minutes, and then take them out. Mix the watercress into the flour, mix well and spread it in a dustpan and enter the fermentation room for fermentation. The temperature is controlled at about 40 degrees.

2. After six to seven days, yellow mold will grow on the watercress, and the initial fermentation will be completed.

3. Put the moldy watercress into the pottery jar, add 5.75kg of table salt and 25kg of water at the same time, mix evenly and then turn it over to dry. The tank should be turned over during the day (that is, stirred and turned), and placed in the open air at night, but be careful to avoid rain.

4. After 40 to 50 days, the watercress will turn reddish brown. Add the crushed fresh chili pepper and the remaining salt, mix evenly, and then store and ferment for 3 to 5 months. The doubanjiang recipe is fully mature, and good doubanjiang will take longer to ferment.

High-quality Pixian Douban is like this. It not only requires high-quality raw materials and complex processes, but also requires nearly a year of natural fermentation, so that it can absorb the essence of heaven and earth and have a mellow and long taste.

There are many Pixian Douban on the market now, so how should we choose one?

First of all, you should choose Pixian Douban produced by regular manufacturers in the regular market, and do not buy three-no products. Because large manufacturers have quality system certification, the quality of their products is more guaranteed. I recommend the brands "Juancheng", "Dandan" and "Chuanlaohui". Each brand has its own series of products, such as "Red". "You Douban" (more red oil), "Chop-free Douban" (already chopped, no need to chop, very convenient), and there are also small packages, one bag at a time is very convenient, you can choose according to your own needs. Many manufacturers will also classify doubanjiang into grades, such as first grade, second grade, third grade, etc. The price difference is huge. The higher the grade, the better the materials and production.

Secondly, it depends on the production date and shelf life. Many people think that Pixian Douban is a fermented food anyway, and the length of time does not matter. In fact, this is not the case. Food is easily contaminated during storage and transportation. Be sure to check Use before the expiry date.

You should choose Pixian Douban with bright red oil, brown-red color and mellow smell. Some inferior and fake Pixian Douban have dark color and many impurities, so be careful.
