PREVIEW: Bake Off Semi-Final (Pictures)

It's the semi-final, and it's Patisserie Week in the tent.

It's the semi-final and the perfect time to test the remaining bakers' skills in patisserie. They face a booze-soaked Signature packed full of flavour, and a testing Technical where they must impress the judges with their pastry horns.

And finally, in the Showstopper, the bakers must demonstrate finesse and precision on both a small and large scale, creating a cube entirely from delicate, smaller cube-shaped cakes. Only three bakers can go on to the final.

The Great British Bake Off continues Tuesday at 8pm on Channel 4.
