Very infrequently, I'll use the fragment "if and as" in a sentence. For instance:
Having it be double fudge chocolate cake in both cases comes off as needless frippery if and as the recipe is valid in itself.
I think I'm using it to mean that the recipe itself can be considered valid by some ("if") and is considered so by me ("as"). But this could be either grammatically unsound or not meaning roughly what I want it to mean.
So is it grammatically sound?
Does it convey what I think conveys?
If so, does this fragment of three words have a formal name for what it's doing grammatically?
