Minecraft wiki entry for Fire_Aspect, associated text: When a mob that normally drops raw meat is killed while it is burning, or if a mob is killed in one shot, even if it is in water, it drops cooked meat. However, enemies damaged through Sweeping Edge that were not directly hit by the sword will not be affected by Fire Aspect. For example, if you swung your sword at a piglin and two other piglins were damaged through Sweeping Edge, only the first piglin would be affected by Fire Aspect.
