The Great British Bake Off (2010)

S5E10 The Final

Title: The Ultimate Showdown Plot: The trio of finalists is put to the test in a Signature Challenge, where they have only three hours to demonstrate their proficiency in a pastry skill that typically requires an entire day. Following this, they'll confront a Technical Challenge that demands their expertise without any guiding recipe. To culminate the competition, they must create a Showstopper that skillfully combines sponge, caramel, choux pastry, and petits fours into a masterpiece worthy of victory.
