Pè-ti chin (sour mung bean sprouts)ပဲတီချဉ်

Green gram (mung beans) is soaked overnight and sprouted for about five days. Meanwhile rice water, rice juice, a trace of salt and turmeric are left to sour on their own, and the sprouts are then steeped in this liquid for one or two days until they are sour, at about pH 3.5.

Recipe

No fixed amounts recordedTraditional small-maker process with no fixed amounts; the study recorded the method by interviewing five to eight makers per food, each with at least two years of experience.

At a glance

Green gram (mung beans) is soaked overnight and sprouted for about five days. Meanwhile rice water, rice juice, a trace of salt and turmeric are left to sour on their own, and the sprouts are then steeped in this liquid for one or two days until they are sour, at about pH 3.5. Made in 4 steps over 6 days – 7 days. The longest step, drain and sprout with a light daily watering, takes 5 days (Bo Bo and Aye Aye Win 2022). Lactobacilli, 6.63 log CFU/g in market samples and Leuconostoc lactis do most of the fermenting.

What makes this one different

The sprouts are not salted to ferment on their own. A sour rice-water liquid is made separately while the beans sprout, and the sprouts are soured in it. In mon-la chin the congee goes straight into the pot with the radish.

Safety

Bo and Win (2022) describe Myanmar's plant ferments as small-scale, spontaneous and not standardised, with inconsistent quality and poor hygiene, and call for quality and safety standards. Their market samples had fermented for less than 5 days. Market pè-ti chin measured pH 3.47 ± 0.07.
