Ok,  this is from Sally wise's book A Year In A Bottle.

1kg of apples (granny smiths have the most pectin content)
3 cups water

Combine apples and water in a large saucepan and bring to the boil and simmer for 45 mins.

Strain through a colander, then strain the resulting liquid through muslin (I may have used a chuck for this when I didn't have musline one day!).  This is your pectin stock!

Any excess pectin can be frozen for use in jams, jellies etc.

Sally also has a great recipe for apple mint jelly if you want that too?

Hi! Do you think that apple pectin can be made in the Thermomix? How?
Thank you very much!
