The Great British Bake Off S08E09 - Patisserie Week - Semi-Final

It's the semi-final of the Great British Bake Off, and the four remaining bakers are all desperate to claim their place in the final. The remaining bakers know they are just three patisserie challenges away from the biggest day in their baking lives. First comes the signature, and there's no business like choux business as the bakers must set to work on producing 24 exquisite choux buns. Prue has set a complex technical for her first semi-final that leaves everyone stumped. And there's a meringue sculpture showstopper where the bakers mustn't crack under pressure. Who has the skill to reach the Bake Off Final and who will leave the tent?
