Interesting reaction, there isn’t anything unusual in it such as flavoring one might be sensitive to, etc. That’s a mystery to me, but just steam (which seems slightly funny considering the name of the blend) and burnt tongue sounds like smoking issues rather than the tobacco. 

I’ve only ever had bad reactions to some flavorings that I seem to be hypersensitive to, which ruin my sense of taste for a couple of days. Half and Half is like that for me, I think of it as half tobacco, half burning polystyrene. Even worse to me is Wilke Peanut Butter, it took four days to get over that experience and I didn’t even smoke the bowl past getting it lit. 

I have had bad reactions long time ago, and I don't rule out the possibility that my inexperience and poor technique were part of the problem, but the reactions were strong enough to avoid those blends forever. The blends were in no particular order:

State Express Roundels, Dunhill Three Year Matured Virginia, Half and Half and Prince Albert.

I have more tobaccos in my "Never again list", but none of them caused me a bad reaction, simple I did´n liked them.

Thankfully, my “never again” list is empty …so far.

But, I have had a very similar “off on the wrong foot” experience. Mine was with Seattle Pipe Club’s “Give Me Liberty” - played out alot like yours at first - but it’s smoking fine for me now.

For me so far it's vapers. Some people love them. I've only had Chenet's Cake and I didn't find it offensive, just not my thing. I parked it for a couple of months and went back with the same result so in my case it's just something my tastebuds don't want.

In your case if you can't find any takers for it I still think if you let it sit for a while you might get a different result.

I never experienced tongue bite smoking English Mixtures, only aromatics, IMO it says something.

I love aromatics, but they were the last one to get used to once i had the worst experiences at the very beginning, after managed a good cadence i really started to enjoy them. After that, i only experienced tongue bite when filled my bowl too tight, so due to the lack of oxygen between the tobacco, i had to sip strongly or lightened the tobacco more times which i believe could improve the burnt feeling. 

About sore throat none of the tin tobaccos i had were aggressive, i was cigarette smoker so the tobacco has to be really rough to make me feel bad in this way.

I’m too inexperienced to have a “Never again list”. There are a few blends I haven’t enjoyed at first attempt, but plenty that I went on to enjoy at a later date. So, I figure I’ll just wait a bit with those blends that don’t tickle my tastebuds in an enjoyable way.

Quite the same experience with Bayou Morning Flake, we really couldn't get along...

HH Burley Flake gives me heartburn for whatever reason, although I otherwise like the blend.

And some MacBaren blends like Dark Twist Rolls, Navy Flake, Plum Cake, Scottish Blend as well as their Amphora aromatics always leave a bitter and tongue-bitey mouthfeel behind, and I smoke slow and never have issues with tongue bite with any other blends. I think it's due to the casing on those blends.

No fui capaz de llegar a consumir ni un cuarto de Blood Red Moon de Cult. Cada fumada era como un shock de azucar... sin mencionar que la lengua me quedaba como globo.

As a new smoker, it mystifies me that one day, a tobacco tastes amazing, and the next I can’t put the pipe down fast enough (looking at you, Stokkebye coins).

But in my own case it’s clearly technique and inexperience.  In time, I’m sure it will make sense. 😕 

I feel like I should not be dishing out advice, but in my personal experience, I have found pipe tobacco to be quite odd and quite unlike other similar things, in that the more I smoke something, the more I appreciate it.

With a lot of other things, I just get sick of it and it turns me off. It's the opposite with pipe smoking.

The post up there somewhere I made about VApers is one example of that. Another is my Marybelone that I've been smoking quite a bit of over the last week. I'm out at my friend's holiday house and I took only a few tobaccos with me (intentionally). One aromatic, one english and one VAper. The English I took was probably my least favourite in my collection - Marybelone. Which is not to say I disliked it. I just wasn't particularly impressed.

After a week of having that as my only English blend, I've really grown to appreciate it. Last night I had a bowl before bed and it was honestly one of my best smokes of the year. Just fantastic. I was sitting there thinking, "why can't it always be like this?". I could really taste the tiny nuances in the tobacco and the dry, fragrant-burning-wood-type flavour of the Latakia and Oriental combination was so deeply satisfying. 

Where as before it was my "least favourite" English in my collection, now I'm starting to freak out about how quickly I'm going through the tin and wondering how many I should buy to cellar.

Had a similar experience with Capstan Navy Blue.

The tongue’s a weird thing, mine can get ruined from all sorts of stuff. Better to just put the tobacco away until I feel “hungry” for whatever tobacco again, and then the romance returns.

On the other hand, after smoking half a can of Warhorse Bar… I just can’t again. The smell of the tin makes me want to puke! Like a Glade air freshener in a hospital restroom. No thanks!

Only those with a steel tongue can smoke Dan Tobacco — Milonga without a tongue bite. 

Tonight I smoked a bowl of C&D Odessa which was OK. Maybe a bit thin compared to my expectations, but quite smokable. But it is very oriental forward and I have a similar dry sore throat, I noticed after smoking Steamworks.. It's minor and no big deal. But I'm wondering if a particular C&D oriental doesn't agree with me. The thing is I've smoked loads of Star Of The East which also features Turkish Izmir. I'd think C&D would use the same Turkish in both those blends.
