For the jam roly poly: place the butter, sugar and flour in a bowl and rub together with your fingertips to make a crumble. Add the candied peel and the milk and bring together to make a dough.
Roll the dough out to a thickness of approximately half a centimetre. Spread the jam on to the dough and then roll up into a log. Wrap the roly poly in baking parchment and tie the ends securely. Place in a steamer and cook for 40 minutes.
For the custard: beat together the egg yolks, sugar and corn starch. Split the vanilla pod in half and add the seeds to the mixture.
Bring the milk to the boil and then add to the egg and sugar mixture. Return to the pan and cook until the custard starts to thicken.
To serve: cut the jam roly poly into slices and serve with warm vanilla custard.
