My favourite type of apple is granny smith.  What about you?
I like to cook with granny smith apples for my apple pie, which is one of the most popular uses of the granny smith apple
It is indeed but I love to eat them raw too.  They originated in Australia in 1868 and were named after the person who cultivated them Maria Ann Smith. She had lots of children and later grandchildren and was nicknamed Granny Smith in her later years.
There is a festival in Australia that honors Granny Smith, and it attracts over 80000 people a year.
