Suppose tissue identical to that of a pig could be created synthetically (with kosher ingredients) in a science lab. The meat would be completely indistinguishable from pig meat, but it would never have actually been part of a real, live pig. Would this be kosher? If so, would it be meat or parve? If beef were created synthetically would it be meat or parve?
My guess would be that both would be kosher and technically parve, but rabbis would rule that it should not be eaten with dairy to avoid maris ayin. Possibly for the same reason, they would rule that the synthetic pork should not be eaten.
Has this been discussed anywhere?
I am referring to a completely synthetic process. For example, supposing the scientists figured out the chemical composition of the tissue and performed chemical reactions to fabricate it rather than growing it from some pre-existing animal cells.
