Yes it is.
I let them ripen before i use them. I cook mine and freeze them, then i add a bit to what ever i want.
I don't use sugar when cooking, use honey. Gives a much better flavour and cook them in the microwave one at a time. Depends on the size of the apple. Only cook them until they're a bit soft, but not mushy because they keep on cooking after.
I hope that will help.
I have no choice and they were picked by ex. He's offloading them to me. When I did the same with my potatoes, he moaned and son was annoyed with both of us! I prefer slowing cooking them. Should I slow cook them and freeze them?
