If i may make a suggestion. If you'd like Community Support (And subsequently, any Development response at all), I recommend removing the word Primeval Brew.
The majority of this forums... 'player base'... foam at the mouth of Abyssea!
That aside sir, I find your idea to be most... interesting. Though If i may be as bold as to make a recommendation. I would probably insist on two foods, Both possibly Abjuration Foods? Something better than Ambrosia, Maybe something like...

--- Both Foods would require an Abjuration to Uncurse.
--- Both Foods require a unique, semi-difficult to obtain Item.
--- Both foods worthy of their hard to obtain stature.
Those are just spitballed ideas. But the idea of another tier of Abjuration foods would be really nice.
