They are wonderful - there was a variety here in WI on my sister’s farm that was pink on the inside; it was 2.5 feet in dia and hollow - fell over in a high windstorm before we could get cuttings.
Then there were several varieties back were I used to live in WA across a creek past a dense forest including some plum and cherry trees from a long gone homestead.
My house in NH was built on an old orchard. Across the stone wall, I would go into the overgrown orchard and grab the few non-wormy apples. They were great.
