My verdict: The jícama by itself has a sweet flavor which is mild and pleasant. But it doesn't really shine until you dump some chile–limón salt on it. I've tried three different brands of chile–limón salt: Lucas , Tajín, and Zumba Pica (you should be able to find at least one of these in any given Mexican tienda). I like the Lucas the best, and then Tajín, but even the Zumba Pica is suitable.
 For those who are unsure why Latter-day Saints (Mormons) go on missions, I recommend you visit here and here, where you can learn more about LDS beliefs concerning sharing the Gospel of Jesus Christ. If you have more questions, ask and maybe I'll do a full post on the topic.
 The mascot of Lucas candies is a duck and every one calls their products Pato Lucas. The company, however, refrains from doing so since Pato Lucas is the trademarked name for Looney Tunes' Daffy Duck in Spanish.
