In Hilchos Shabbos there is a rule called bishul achar afia (the opinion of the R'eim, cited in Tur O.C. 318 and Shulchan Aruch 318:5 and brought as the minhag by the Rema) which means, basically, that heating through an air medium and a liquid medium are two different types of heating, and applying one to a food item even after the other has been applied may constitute a violation of Shabbos through cooking.
Is there such a rule in bishul akum? If a Gentile takes baked bread and deep-fries it, does it become prohibited as having been cooked by the Gentile?
Does the fact that it is edible as a result of the first type of heating before the second type of heating was applied to it make it considered "edible raw"? I.e. before it was ever baked, it wasn't edible, but before it was boiled/fried, it was edible as a result of the baking. So do we look at the food as it is immediately before cooking it, or as a type of food which isn't eaten raw?
