Wikipedia has that this is not the common-use definition of "acronym", though some argue for it. In the common-use sense, an initialism is just one type of acronym.
For some, an initialism or alphabetism, connotes this general meaning, and an acronym is a subset with a narrower definition: an acronym is pronounced as a word rather than as a sequence of letters. In this sense, NASA /ˈnæsə/ is an acronym but USA /juːɛsˈeɪ/ is not.
The broader sense of acronym, ignoring pronunciation, is its original meaning and in common use. Dictionary and style-guide editors dispute whether the term acronym can be legitimately applied to abbreviations which are not pronounced as words, and they do not agree on acronym spacing, casing, and punctuation.
How about gremolata, chimmichuri, creamed mushrooms, caramelized onions, wine and balsamic reductions?
Hell, just salt and fucking pepper alter the flavor of the beef.
No need for food snobbery at all.
The only problem with people using bottled sauces is that it may not be equally effective for their needs if it isn't the right cut of steak. An a1 type of sauce gives a different end flavor on something like a rib eye than a filet because the fat levels and "beefiness" aren't the same.
Now, me? If I want steak, I want steak, not sauces, so the most I'm going to put on top is something like a pan sauce where I deglaze with bourbon and let it reduce enough to nix the alcohol flavor but still pick up the fond.
But that's me. I ain't mad at anyone having food the way they like it; might not be willing to buy a filet for someone that insists on well done for everything, but I'll be glad to hook them up with a cut that works when well done so that I'm not wasting money on something they won't enjoy as much.
