Apple Crumble

In our garden we have an old apple tree that I think is over a hundred years old. It is the last from an orchard that used to be on the site before these houses were built over 86 years ago. It is the biggest apple tree I have ever seen and although is partly falling down, as the roots have been pulled out of the ground over the years and it is leaning slightly, each year it still has an impressive amount of fruit and some very big ones too. It is obviously some kind of cooking apple due to the sheer size of the apples but they are actually quite a lot sweeter than Bramleys. Maybe they are from an apple that is no longer used. If anyone has any history of old types of apples please let me know. Anyway the last of them are now falling to the ground and the other day I made a crumble for my family and mainly for Marcus, my middle son. Since he helped his grandma make one a few weeks ago he has took a great liking to them and asks for one a lot. This one didn't fail to deliver and was thoroughly enjoyed by all. The remainder of the apples shall be left on the ground for the thrushes and the insects to happily devour and hopefully the tree shall live out plenty more years of crumbles.
