Line two large baking trays with grease proof paper.
Lightly dust a work surface with flour and turn the risen dough out.
Roll it out into a large rectangle (roughly 24 inches by 12 inches), lifting it regularly to make sure it's not sticking to the work surface.
With the longest side closest to you, spread the jam over the left half of the dough.
Fold the right hand side of the dough back over the left hand side of the dough so that the jam is completely encased.
Cut 12 long strips and separate them from each other.
Take the ends of the first strip in either hand and twist.
Placing the twisted piece of dough back on the counter top, curl one end up until a spiral has formed.
Place the twisted bun on to the baking tray and repeat with the rest of the dough.
Leave the twisted buns to proof for a further 30 minutes. In this time pre-heat the oven to 180C / 350F / gas mark 4.
Place your baking trays into the centre of the oven and baked for 20 minutes or until the buns are golden brown.
Leave them to cool for 10 minutes on their baking tray before transferring to a wire rack to cool completely.
