I really like apples, especially Granny Smith
Yum they are hard with light green skin but that crisp and juicy flesh makes them the best!
Yes! They taste nice in desserts like apple crumble as they are quite tart. What's your favourite type of apple?
I like Grammy Smith because it so easy to make in cooking anything that needs apples.

Granny Smith
The Granny Smith is a tip-bearing apple cultivar, which originated in Australia in 1868. It is named after Maria Ann Smith, who propagated the cultivar from a chance seedling. The tree is thought to be a hybrid of "Malus sylvestris", the European wild apple, with the North American apple "Malus pumila" as the polleniser.
The fruit is hard, with a light green skin and crisp, juicy flesh. The flavour is tart and acidic, which possibly limits raw consumption.
