“Pamplemousse” is the French word for grapefruit. While it’s a common term for grapefruit in French, in some cases, it might specifically refer to the pomelo, while “pomélo” refers to the grapefruit. I was informed today by a local that there are 200 different varieties of pamplemousse on Hiva Oa, and each has its unique properties. For example, these two are both ripe. The one on the left is supposed to be yellow before it is eaten. The one on the right is ready when the center part shown turns white, which it has.
