At a glance
Oi-sobagi is cucumber cut into short pieces, slit into four, salted and stuffed with chopped chives or green onion, garlic, ginger and chilli. It sours fast and is eaten within days, crisp and fresh, in spring and summer. Made in 5 steps over 24 h – 8 days. The longest step, ripen briefly and eat, takes 24 h – 8 days (National Folk Museum of Korea 1948) and runs at 10 °C (Paik J.-E 2006). Lactobacillus plantarum, Lactobacillus sakei and Leuconostoc mesenteroides, detected by PCR in oi-sobagi does most of the fermenting.
Water oi-sobagiThe older form, with brine poured over the stuffed cucumbers.
Gaji-sobagi (eggplant)Eggplant slit and stuffed like oi-sobagi, but blanched first (see gaji kimchi).
Safety
Kimchi is not a common vehicle of foodborne pathogens, because lactic bacteria work against them, but a review of Korean fermented foods warns that this cannot be taken for granted. In one study of kimchi stored at 10 °C for 7 days, E. coli O157:H7, Salmonella Enteritidis, S. aureus and L. monocytogenes all survived, and E. coli O157:H7 stayed high through 24 days (Inatsu et al. 2004, as reviewed).
The farm manual Jeungbo sallim gyeongje, whose manuscript was completed in 1766, records hwanggwa damjeo beop, cucumber stuffed with chilli and garlic, the first written oi-sobagi. Imwon gyeongje ji and Siui jeonseo give the green-onion, garlic and chilli filling used today. Chives became the main filling after the 1980s.
