Not quite as exciting as some years ago now when I wondered why limes had disappeared and learned that some of "my" lime growers were in the middle of gun battles with crime cartels trying to take control of their orchards. Old news now, criminals largely control the industry in Mexico, much the same for avocados, which are now being called by some "green gold" and others "blood avocados."
But when ingredients can come from various parts of the planet, all kinds of things might be going on.
