Is there a reason we can't grow apple trees?
I find it odd that such an obvious thing is missing from the fields. Then I figured we got them from an island but apparently not.

They have such versatility, too. Apple's could go on to be apple butter in the jam factory, caramel apples in the candy factory, apple pie/crumble/cobbler/turnover in the pastry factory, apple cider in the beverage factory, all with other stuff that's already available. Apple loaf in the bakery.
Apple syrup in the sugar factory.
Just a thought.
