Description

Traditional Korean fermented soybean paste made with just soybeans, salt, and time. This doenjang develops deep umami flavor through natural fermentation.


Ingredients

Scale
  • 2 pounds dried soybeans
  • 1 cup sea salt (for brine)
  • 1 gallon filtered water
  • 23 dried red chilies (optional)
  • 1 small piece natural charcoal (optional)
  • Cotton string for hanging

Instructions

  1. Sort and rinse soybeans. Soak in water for 8-12 hours until doubled in size.
  2. Drain and cook soaked beans in fresh water for 3-4 hours until completely soft.
  3. Drain and mash warm beans into chunky paste. Form into 4×4×2-inch blocks.
  4. Dry blocks on towel in warm location for 7-10 days, turning daily.
  5. Tie dried blocks with string and hang in warm spot (70-75°F) for 6-8 weeks.
  6. Brush off surface mold and break fermented blocks into chunks.
  7. Dissolve 1 cup salt in 1 gallon water. Place chunks in jar and cover with brine.
  8. Add chilies and charcoal if using. Cover with breathable fabric.
  9. Age in cool, dark place for 2-3 months, checking weekly.
  10. Strain liquid (save as soy sauce). Mash solids into paste and store in refrigerator.

Notes

White or blue-green mold is normal and beneficial. Discard any blocks with black, pink, or red mold. The paste continues developing flavor in the refrigerator for up to one year.
