Roll the dough out into a rectangle. It doesn't matter how big it is, just as long as the thickness is the same throughout. If the dough struggles against you a little, cover it and leave it to rest for five minutes.
Evenly spread the cream cheese filling in the centre third of the dough (I usually measure and then score the thirds gently with a knife, as this makes it easier). Don't spread the filling right up the top (or bottom), but leave around 1cm (½ inch) edge.
Dollop the raspberry jam on top of the cream cheese and spread it over evenly.
Taking a knife or pizza cutter, start to cut strips of around 2cm (¾ inch) thickness down both sides. Don't cut right up to the middle section (where the filling is), but leave a small gap.
Turn the top edge of the dough over the filling and then starting off with the top left strip, place over the filling at a slight diagonal. Do the same with the top strip on the right side.
Continue to alternate all the way down to create a criss-cross effect.
Skip the last strip on either side, and turn over the bottom of the dough (as you did at the top).
Finish off by placing the last two bottom strips over the filling.
Seal both ends a little by pinching the dough together at the seams.
Cover and leave to rest for 30 minutes. Pre-heat the oven to 175℃ (350℉).
When ready, give the top of the braid a good wash with the egg.
Sprinkle over as much pearl sugar as you like.
Bake in the lower part of the oven for 20 minutes (start checking at the 15 minute mark).
Allow to cool before slicing (it's much nicer cold). Enjoy!
