Does anyone have the minhag to eat AMaLeK kugels? Apple Meal Lukshin and Kertufel?
Anyway, I think all (kosher) foods have (real) kavanos to them. If you know how to make gematrios you know that almost anything is possible if you know what to look for. I don’t think any food has a kedushah mitzad atzmo. Some as Mod-80 said have more chashivus.
What is true though, is that as a holy people we have the ability to raise food above its mundane state with our kavanos. The sefer Shulchan HaTohor is a well known example of that.
It was explained to me once that every action that we do has its parallels in shamayim in the holiest of places, even going to the bathroom. If we would be able to really integrate into ourselves how much every action we do as Jewish people moves worlds and worlds we would be afraid to lift a pinky not in service to Hashem.
