Our Gemara on Amud Beis discusses the concept of bitul, nullification of a non-kosher substance by a kosher majority to the point that the taste is no longer perceived. This can be determined by having a Gentile Chef (Kafila Arama’ah, literally an Aramite Chef) taste it to determine if there is any taste leftover from the non-kosher substance, or what is generally estimated by the rabbis as a ratio of 60 to 1.

Bnei Yissachar (Adar II:7) offers a mystical explanation for these halachos. There is a spark of divine goodness in everything, even forbidden foods, after all, everything comes from God. However, the forbidden food has impurities that are too powerful to be absorbed and neutralized. God arranges that the sparks of divinity end up in a non-kosher substance that became permitted through bitul. This is why it is a foolish piety to abstain from a food that became legitimately permitted through the process of nullification, because it really is the divine will, that it be liberated through the holy consumption of a person who will use it to serve God.

I will add a thought. Our Gemara also allows the Kafila Arama’ah, an Aramite Chef, to determine if there still is a residue of perceptible non-kosher taste. Who is this Aramite Chef? In the Torah text, the Aramite is Besuel and Laban’s side of our family tree that was idolatrous and thieving, yet also the family that produced the matriarchs Rivka, Rachel and Leah. They too obviously had divine sparks. The Aramite can be seen as the bridge person, not fully a gentile but not fully Jewish. He is therefore the middle stage in the process of liberating the divine sparks.
