While in Kauai where the citrus are varied and amazing, I would prepare different juices every night and do a quick extraction of citrus peels (any of these alone or together: Meyer lemon, lime, kalamansi, buddha hand lemon,...) in a vacuum chamber. About 5 minutes (5 cycles of 1 minute) in white rum.
Amazing how much citrus flavour ends up into the drinks.
