Yes precisely. I was hoping someone would reply with that. The Granny Smith starts of as an acidic yellow ball of death, progresses through a window of being edible over the space of 2 days and then instantly turns into a rotten fermenting mushball suitable for cider only. To get the things, you have to pick them early and check every day and add sugar to whatever you're cooking or they're inedible. For reference, if you buy a Granny Smith in the shop and it's an eating apple, it's probably a hybrid and not a Granny Smith.
