Tooa-li-song-dorng is sprouted peanuts mixed with about 10 % salt by weight and left closed in the shade for 2 to 3 days. Some makers add rice-wash water, which shortens how long it keeps. Thai peanut sprouts fall under the community product standard for pickled bean sprouts, which requires pH 4.0 or below.

Tooa-li-song-dorng is sprouted peanuts mixed with about 10 % salt by weight and left closed in the shade for 2 to 3 days. Some makers add rice-wash water, which shortens how long it keeps. Thai peanut sprouts fall under the community product standard for pickled bean sprouts, which requires pH 4.0 or below. Made in 3 steps over 2 days – 3 days. The longest step, close in a jar or bowl and ferment in the shade, takes 2–3 days (JIRCAS 2026). Salt is 10 % (JIRCAS 2026).
Tooa-li-song-dorng is mixed with dry salt rather than covered with the salted vinegar water of its mung-bean cousin. Some makers also add rice-wash water, which shortens how long it keeps.
Thailand's community standard for pickled bean sprouts names peanut sprouts in its scope. It requires pH 4.0 or below, total microbes no more than 1 × 10^4 per gram, no Staphylococcus aureus in 0.1 g, E. coli below 3 per gram (MPN) and yeasts and moulds no more than 100 per gram. The FDA says sprouts served raw or lightly cooked can carry Salmonella, Listeria and E. coli, because the warm, humid conditions of sprouting let a few bacteria on the seed grow to high levels. It says children, older adults, pregnant women and people with weak immune systems should avoid raw or lightly cooked sprouts. This recipe has no heating step [fda-produce].
Hazards the sources name: Staphylococcus aureus and Escherichia coli (the standard sets limits for both).
Thailand's Industrial Standards Institute issued Community Product Standard 319 for pickled bean sprouts in B.E. 2547 (2004), and its definition names peanut sprouts alongside mung-bean sprouts.
