Since she was still able to complete the round, the judges continued with evaluating her bake, deeming her a candidate for elimination alongside Georgie and Hazel.
The ten remaining bakers were asked to carry out three challenges. The Signature Challenge was to make twelve identical savoury buns which had to be from an enriched, yeast-based dough, but could be any flavour and any shape. The Technical Challenge let the bakers watch Paul Hollywood demonstrate the plaiting of seven strands of dough to form a wreath before they then repeated the exercise. The final Showstopper Challenge this week was to make acornucopia, also called a 'horn of plenty', filled with at least two different types of bread.
The nine remaining bakers tackled caramel this week throughout the three challenges. For the signature challenge, the bakers were asked to make 12 identical caramel biscuits. For the technical challenge, they were tasked with making a classic pear tarte tatin. For the showstopper, the challenge was to make a caramel mousse with at least two types of caramel.
The seven remaining bakers faced three challenges themed around autumn. For the signature, they had 2 hours and 45 minutes to make a decorative pie with autumnal flavours. The technical recipe was Prue Leith's vegan adaptation of a traditional parkin; the bakers had an hour and a half to complete the challenge. The showstopper required them to produce elaborate vegetable cakes themed around an autumn festival.
The six remaining bakers were tested on their dessert-making skills. The signature challenge was for eight mini meringue nests with two fillings, to be completed in two and a quarter hours. For the technical, Prue Leith tasked the contestants with making a traditional English pudding: the spotted dick. The showstopper asked the bakers to put their own spin on a classic Italian tiramisu; they had four and a half hours to complete this challenge.
In the quarterfinal, the five remaining bakers were given three retro challenges, taking them back to the 1970s. The signature required them to create a decorative stack of at least 30 profiteroles. The technical was Paul Hollywood's banoffee pie. Although the bakers were given ingredient measures, they did not have any instructions for how to make the pie. The showstopper challenge was to make a '70s-style tiered gateau.
