Pla ra with mixed freshwater fish
Mixed freshwater fish are soaked, repeatedly washed, salted and packed with toasted ground paddy rice; the creator gives a 1.5 kg fish batch and an unmeasured ladle dose.

Pla-ra jar with bamboo pressing mat
ปลาร้า ไห กระด้งไม้ไผ่ · ປາແດກ ໄຫ · padaek jar
A narrow-necked earthenware jar for pla-ra fermentation, with woven bamboo strips pressed over the fish to keep it beneath the liquid. The jar is covered while allowing overflow; no standard size or lid design is established.
A narrow neck and an internal restraint
JIRCAS describes pla-ra made for longer fermentation in narrow-necked earthenware jars. The fish are packed in the jar and covered with salt. As liquid emerges, woven bamboo strips are pressed over the fish to hold them beneath the liquid. The jar’s neck constrains the opening around this internal restraint. It is a functional part of the fermentation setup, not a decorative basket placed around the outside.
The source specifies earthenware and bamboo, but gives no clay recipe, glaze or firing details. It also does not provide a standard capacity, neck width or mat diameter. The Thailand Foundation’s photograph shows many jars used for fermenting fish; it does not show the hidden bamboo strips, so it is evidence of jar use rather than a depiction of the complete jar-and-mat assembly.

Covering the jar without sealing away overflow
After the bamboo restraint is placed, JIRCAS says the jars are covered to protect the fish from flies, while excess liquid is allowed to overflow. The jars are usually kept in shade. This description explains why a sealed modern bucket or a lid that traps all overflow would not be a faithful stand-in for the documented arrangement. The source does not specify a particular cover material or fastening method, so this account leaves those details open.
The restraint has a defined job: keep the fish under the liquid as fermentation proceeds. JIRCAS describes the later mixture being packed in earthenware jars and left for at least six months. That duration is the source’s account of pla-ra, not a fixed operating rule for every jar, region or producer.

A regional vessel form, not one universal pla-ra jar
JIRCAS lists plaa-daek as a northeastern Thai name, while its entry also records plaa-ha in the north and ra in the south. The Thailand Foundation places pla ra prominently in Isan and notes regional differences in ingredients and preparation. The jar described here belongs to a documented Thai method; those names do not prove that every regional fermented-fish tradition uses the same vessel or bamboo restraint.
The inspected sources establish the jar’s material, restricted neck and the bamboo restraint’s purpose, but not a single shape profile, size, glaze, firing, or long-term care routine. Some production photographs show groups of earthenware jars, but the hidden interior arrangement must be described from the method evidence. Exact measurements and construction details should be added only when a source identifies the particular vessel.

Made of
- earthenware — fermentation jar
JIRCAS describes narrow-necked earthenware jars; it does not specify clay body, surface finish, firing or dimensions. - woven bamboo — internal restraint
Woven strips pressed on top of the fish keep it beneath the liquid; the archive also records a woven disk or interlaced strips fitted within the restricted mouth.
Limits
The bamboo strips are documented as a way to keep fish beneath liquid; the sources do not specify one universal mat size, weave or jar fit.

Plaa-raaFor longer pla-ra fermentation, JIRCAS describes tightly packed fish in narrow-necked earthenware jars, salt covering the fish, and woven bamboo strips pressed on top to keep fish beneath liquid.
The account says jars are covered against flies while allowing excess fluid to overflow, are usually kept in shade, and the final mixture is packed in earthenware jars for at least six months.
The database gives plaa-daek as a local name in northeastern Thailand and notes regional names including plaa-ha and ra.
