making seville orange marmalade

[sophy]

want to try my hand at making seville orange marmalade.

Have never made marmalade or jam before.

Top tips? thanks

bump - anyone marmalade experts out there?

Sophy - I've got some cooking at the moment. Seville oranges are only available during January - first half of February. My recipe involves softening the fruit in a pressure cooker but will post it if anyone is interested.
Surely there should be a competitive marmalade thread as there have been for Victoria Sponge etc?
