Over‑fermentation leading to overly sour or alcoholic flavour.
Excessive salt causing overpowering salinity.
Using low‑quality tuna resulting in off‑flavours.

Provenance

Rihaakuru originates in the Maldives, where it has been produced for centuries by fishing communities as a means to preserve tuna and enrich dishes. Its preparation combines fermentation with reduction, a technique adapted to the tropical climate. The condiment is now considered a defining element of Maldivian cuisine.
