Headcannon: love can have varying tastes, like how puppy love, like what one would give to a nymph, tastes different then the kind of love one gives to a girlfriend. sometimes the drones will eat various different foods to spice up the taste of the love they get from papi and what they give to papi in return.
A very fun and usable headcanon. I see love varying in taste depending on the giver and the receiver as each individual would feel love differently, and accept love differently.
As for the food changing flavor idea, I love it.
