Young goats and mother's milk

[True Federalist (진정한 연방 주의자)]

Exodus 23:19, Exodus 34:26, and Deuteronomy 14:21 all contain the same prohibition about not cooking a young goat in its mother's milk, or at least that's the conventional interpretation.  It seems like an odd prohibition and as I understand it, the Talmudic scholars of the 2nd century simply accepted it as unexplainable with some speculation about an old heathen rituals.

However, I had a thought, which fits my limited understanding of Hebrew grammar, so it could be completely wrong.  There are several people here with a better understanding than me, so I figured I'd see if anyone here can disprove my speculation which concerns the meaning of the preposition ב.  Instead of "a young goat in its mother's milk" what if the intended meaning was "a young goat on its mother's milk" or to put it plainly: an unweaned kid.  The Bible includes a number of poetic ways of expressing concepts and that prohibition is not as inexplicable as the one traditionally given.

Of course besides an improper use of grammar, it's possible I've overlooked some other passage that would argue against my speculative interpretation.

Well, kashrut certainly generalizes the literal meaning of that prohibition far beyond a de minimus restriction, with highly observant Jews choosing to not even mix meat and dairy in the same meal, let alone the same dish.

Eh. I've seen Jewish people eat pork but recoil at the site of putting cheese and pork on the same slice of bread.

How long did they avoid that location?  Several days or only until the sandwich was eaten and out of sight?

Oy vey.

If you want to have differently spelled words mean different things, I suggest pronouncing them differently.

"In its mother's fat" makes even less sense than "in its mother's milk", so I'm slightly surprised that isn't the tradition.

More seriously, I'm glad to hear that grammatically "on its mother's milk" makes sense.  At worst the alternate interpretation I've put forth is a broader version of the literal meaning of the traditional interpretation.  Of course, if one takes the flights of fancy concerning the separation of meat and dairy found in kashrut as your basis, my alternate doesn't support that.  But then if I were a Jew I'd lean towards being a Karaite anyway, so that doesn't bother me.
