Doenjang
“Fermented soybean paste, the byproduct of soy-sauce-making. Coarser, chunkier, and funkier than Japanese miso. Base of jjigae and ssamjang.”
Where it comes from
Three Kingdoms period (57 BC-668 AD); the 1610 Donguibogam medical compendium prescribes it for digestive ailments. The traditional method splits a meju (soybean brick) ferment into liquid (ganjang/soy sauce) and solid (doenjang) at the salt-pulling stage — a uniquely Korean two-product technique.
On the plate
Dark khaki-brown paste with intact soybean halves, gritty texture, almost-cheese funk in the aroma. Salt heavy, umami deep, slight bitter. Stirred into doenjang-jjigae with anchovy stock and zucchini, or thinned with sesame oil + scallion as ssamjang dip.
How it works
Meju bricks ferment 40-60 days at 25°C with native Bacillus + Aspergillus, brining 60+ days in 18% salt brine. Liquid drained off as soy sauce; solids re-aged 6-24 months as doenjang. Bacillus-driven (vs Aspergillus-driven Japanese miso) — funkier, less sweet, more pungent.
Korean cultural heritage UNESCO listed jang-making in December 2024. Korea's largest doenjang producer Sempio (1946) ages traditional jang for 36 months at its Icheon facility. The chef at Mingles, Seoul (2-Michelin), sources from a Goesan family that has aged in the same onggi since 1893.
Variations
Jaerae-doenjang (재래, traditional 12+ month), gae-ryang-doenjang (개량, modern fast-ferment with koji-only), Sunchang doenjang (sweeter), Goesan doenjang (Chungbuk, deeper umami), and the supermarket Sempio / Chung Jung One brand standards.
