What to do with 500 peaches

Hi Guys, this is my first post about what i have been doing over the break from school. I've seen so many of your awesome posts so thought i had better give it a go myself!
I'm really lucky to have lots of fruit trees at home so i have been busy picking (and eating!) them. I've got apples, quinces and peaches all ripe at the moment so have been trying to find lots of ways to use them all up! So far i have been freezing them, have made peach and ginger jam and peach chutney. Ive stewed some apples and might try and make quince jelly! I would love to hear if you have been doing any cooking and what you have come up with!
