I really like Granny Smith apples. Can you tell me anything about them?
I love cooking with granny smith apples that have such a great flavor for a cooking apple. From my memory the origins are a bit fuzzy, but they were an accidental discovery by a lady in Australia in 1868.
Oh wow was she a Grandma by any chance lol.
I imagine she was, the apple variety was discovered shortly before her passing. She gave birth to 8 children in her life, 5 survived infancy so I would say there was a good chance she had grandkids. 
Well that is quite a progeny. I am sure she has many ancestors. So what color are the apples, red?
Granny Smith apples are typically green and turn yellow when they are over-ripened (aka rotten). They are a bit tart. 
Oh ok. I seem to remember they are often dipped in caramel and sold at fairs. They are quite delicious.
They are also good for eating raw or dipped in caramel. From what I understand she found the tree growing out of a pile of her rubbish and it actually had really good apples. It is theorized that one of her apples trees cross pollinated with a crab apple.
