Reading the bitterness

In Okinawa, 「ンジャナバースーネー」 (njana baasuunee), a dressed or shiraae dish using hosoba-wadan (njanabā), is listed as a regional bitter dish in the prefecture’s traditional food culture database. The sources differ in their preparation methods, describing soaking in water or briefly boiling, and do not record a single fixed recipe.

A paper on Okinawan native vegetables states that the distinctive bitterness of Momordica charantia, called 『ゴーヤー』 (in translation: goya) in Okinawa, derives from momordicin, which is contained in the peel. The statement has no citation number, and the text does not make clear whether it reflects primary data or summarizes general background knowledge.
