As a mortal, I believe I am afforded the opportunity to have a few indulgences which I know I will have to answer for at the pleasing judgment bar of God someday.
Some may have indulgences like porn, video games, gambling, drinking and knowingly voting for socialists. I don't judge these people, and with the exception of the latter category, I tend not to avoid them, either. But if you want to avoid me after reading my #1 indulgence, I'll understand (I'll be sad, but understanding).
My #1 indulgence: I. Love. Hot. Chocolate.
I also confess that as Fall progresses and the advent of Winter is nigh, my wife and I plan to totally indulge in copious amounts of hot chocolate until next Spring. In fact, we plan to get some half-n-half, pour in 1-1/2 packets of hot chocolate, mix and nuke that sucker up until there is steam wafting from the chocolately deliciousness.
Sinful? Decadent? Degenerate? Corrupt? Immortal? Damn straight it is, boss! It's a genuine, bona-fide Word of Wisdom violation:
Yes, D&C 89:9 says my drinking hot chocolate runs contrary to the Word of Wisdom (ditto for soup, warm broth, Ovaltine, Postum, Japanese mugi-cha and herbal teas such as, chamomile, ginger and peppermint, which contain no caffeine at all, but let's just stick with hot chocolate for now).
I know there are many who would say "But…but…" and begin giving me interpretations of that scripture. BUT BUT do you see an asterisk or exception anywhere in or around "hot drinks are not for the body or belly"?
Here, let's go back to the Joseph Smith Papers to see if there's an asterisk there:
Nope, no asterisk nor explanation there. There is an explanatory footnote (#15) in the right-hand panel, which says "Several other early nineteenth-century authors argued that any liquid taken at a high temperature could cause injury." But that provides no exception to the scripture. 
Explanations about Hot Chocolate's Sinful Status
In Bush's article (here), he admits that "The subject of "hot drinks" is a little more complicated. "While he admits that "Both tea and coffee were considered mild stimulants," here in the 20th and 21st centuries, drawing a conclusion that caffeine is the culprit is a little complicated. A cup of Swiss Miss cocoa mix has 5 mg of caffeine  - far less than a can of Diet Pepsi (35-38 mg). 
But I diverge from the issue of hot-ness. Bush's article correctly points out that at the time the Word of Wisdom was written (Feb 1833), liquids (such as soup, tea, and coffee, taken at a very high temperature) were considered "injurious." I always knew there was something about Campbell's Chicken Noodle Soup that was injurious!
For more insight, I turned to the General Handbook of Instructions, which says:
Saying that Prophets have clarified that the teachings in D&C 89 include abstinence from hot drinks (tea and coffee) really doesn't tell me anything new.
It may have started with Hyrum Smith, who said, "Again, hot drinks are not for the body or belly. There are many who wonder what this can mean, whether it refers to tea or coffee, or not. I say it does refer to tea and coffee." "I say" is hardly a definitive doctrinal statement per the Law of Common Consent. 
I found 22 references to "hot drinks" in the Scripture Citation Index. In a 1963 talk, Boyd K. Packer once said that "hot drinks -- understood by the Church to mean those with habit-forming potential, specifically coffee and tea" is the perpetuation of an unofficial interpretation of D&C 89:9. 
In 1945, Joseph F. Merrill took things a step further, saying "hot drinks is enjoined, because they are not good for man. By hot drinks was meant primarily tea and coffee, though subsequent researches found that any drinks at high temperatures, such as hot water and soups, are harmful. The ideas voiced in the Word of Wisdom were expressed in words having the meaning current at the time. In those days hot drinks were commonly understood to be tea and coffee." 
Yet Merrill's statement that "hot water and soups, are harmful" isn't accompanied by any double-blind, placebo-controlled studies (the kind which wise and thoughtful medical experts and government leaders gravitate to). It is, in fact, pure speculation ("the forming of a theory or conjecture without firm evidence"), which Ronald A Rasband recently denounced when it comes to seeking answers concerning our health. 
In the April 7, 1868 General Conference, George Q. Cannon gave us a definitive interpretation: "Almost every elder who has spoken from this stand has felt the necessity and importance of calling the attention of the people to this subject (the Word of Wisdom). We are told, and very plainly too, that hot drinks-tea, coffee, chocolate, cocoa, and all drinks of this kind are not good for man." 
But then again, a forgetful Apostle Mark E. Peterson said in 1962 that "At no time has cocoa or chocolate been included in the prohibitions of the Word of Wisdom, and at no time has the Church said that cocoa is as harmful as coffee. Those who make these claims do so on their own responsibility, and obviously without knowing the facts of the matter."  So much for "clarification."
I've thought about writing a letter to Pres. Nelson and asking him for guidance. After all, who better than a worldwide cardiac expert / global faith leader / revelator all in one to answer my question about hot chocolate? But alas, I know that the Brethren would refer my inquiry back to my stake president. He would call me in for a meeting just to refer me back to the General Handbook of Instructions. This is known as an "endless loop" (which is very common among members seeking answers).
Luckily, Pres. Nelson's 1st Counselor has come to the rescue. Dallin H. Oaks said, "The shield the Lord gives to the faithful also protects us against our own harmful impulses. The revelation that commands modern Saints to refrain from alcohol, tobacco, hot drinks, and other harmful things promises the faithful that "the destroying angel shall pass by them, as the children of Israel, and not slay them (D&C 89:21)." 
If what Oaks says is true (and knowing that the church's prophets, seers and revelators would NEVER mislead us), I am now praying that the destroying angel has mercy on me and won't slay me…
…all because I drank hot chocolate.
Today: Please leave me a comment (below) with the best hot chocolate brand/recipe, and why. I figure if I'm going to sin and even be destroyed by an angel for sipping hot chocolate, I might as well do it with style and panache.
Whenever: The next time you're having some casual conversations with a member, ask them if they think it's important to obey the Word of Wisdom. (They'll likely say yes). Then ask them about abstaining from hot drinks. Then ask them about hot chocolate. If they say it's allowed, ask them where it says so in D&C 89. If they say church leaders have said it's just tea and coffee, then ask them when that revision to D&C 89:9 was voted on by church members. Let me know how it goes!
