That is an easy question for me as I always buy Pink Lady apples.
They are sweet, yet have a tang - they are always firm (if you buy at a good fruit shop), and they are just delicious (no pun intended!)
PINK LADY APPLES - yeaaa
Last week my favourite fruit shop did not have any, so had to get others and nowhere near as good.
Granny Smith. I rember when growing we didn't have anywhere near the choice of apples so it was Johnathon ar Granny Smith, the latter we sometimes ate with a sprinkle of salt. When we visited my Great Aunt who lived in the Blue Mountains she had a crab apple tree in the backyard and it was a treat to enjoy these apples.
I really enjoy a perfect Golden Delicious, but these do not seem to have a very prolific season! So I then tend to go for Pink Lady or Fuji, though a good crisp Granny Smith is so perfect to cook with!
Any apple that I see picked. So often get disappointed when buying apples. I think they are kept for too long in cold store. But I love all apples and especially apples in cooking, as long as the cook doesn't get too economical with the apple content.
Royal Gala first, golden delicious next, Grannies for cooking. The sweeter apples are my favourite to munch on. I have been buying bags of "the odd bunch" apples - don't know the variety - and they have been great to eat too, yum.
