Pak sian dong (pickled spider plant)ผักเสี้ยนดอง

Sour pickled Cleome; fermenting softens the raw leaf's bitterness (typical). Made in 3 steps over 2 days – 3.1 days. The longest step, ferment in shade, takes 2–3 days (JIRCAS Database of Fermented Foods of Thailan…). Salt is 2–4 % (JIRCAS Database of Fermented Foods of Thailan…). Lactobacillus plantarum and Lactobacillus sp. do most of the fermenting.
