This apple is probably haunted. Either way, I don't recommend eating it. Created in Blender 2.83
Setting the scene. Props/textures from Quixel
The apple "tear" effect was creating using a combo of some (admittedly messy) boolean subtraction using a modified plane and the SimpleDeform / twist modifier
For the interior I took a photo of two apple halves and UV mapped them onto the two apple half models
