Lemon, Strawberry & Pink Champagne Cake

This will be a thank you post dedicated to everyone involved in the London Inter-University Bake Off, with the recipe of my entry as a thank you gift :)

The Bake Off was a joint event with University College London (UCL), King's College London (KCL), Queen Mary University of London (QMUL) and was held at the London School of Economics (LSE) with proceeds going to the Target Ovarian Cancer charity. We had a total of 52 entries for both the 'Sweet' and 'Savoury' categories and raised £299.70.

Those numbers were way above my expectations and I'm extremely grateful for the overwhelming response from the competitors, the people who came to taste and vote for their favourites, the judges and for the assistance provided by the baking society committees of UCL, QMUL and KCL. Most importantly, I'm thankful for my supremely capable LSE Baking Society committee, who managed to make our last event so successful. Pulling off this event of such scale is something to be proud of considering we're a new society with limited funds and no prior experience.

On a personal note, I would like to thank all my friends for coming down to the event and staying till the end to help clean up. And a special shout out for my dear #foodiesoulmate @nyoncat for providing emotional support and constructive criticisms during this stressful period. I love and treasure each and every one of you.

And so this is farewell, to my baby, the LSESU Baking Society. If you're a prospective/ current LSE student, do join the society next year because I know our newly elected committee is quite possibly more awesome than us.

This took home first place for the Judges' Prize and Popularity Prize in the 'Sweet' category.

Assembly
1. Place a 7 inch round cake ring into a container that has been lined with baking paper. Pipe a thin and even layer of mascarpone cream onto the base of the cake ring and up the sides. Place it in the freezer.
2. Using a 6 inch cake pan, cut out two 6 inch circles of cake from the huge sheet of cake. Brush each cake layer with the wine.
3. Once the first layer is frozen, pour a thin layer of lemon cream. Place one layer of cake on the lemon cream layer.
4. Pipe a thin and even layer of strawberry cream over the cake. Place the strawberry jelly onto the cream and press down gently. Cover the jelly layer with more strawberry cream.
5. Place the last layer of cake over the strawberry cream and seal it with more cream. Place in the freezer.
6. Once the cake is frozen, make the glaze.
7. When the glaze has cooled to 30-40°C, unmould the cake and place it on top of a mug. The white mascarpone cream layer should be on top while the strawberry cream layer should be at the bottom. Glaze the cake. Place the glazed cake on a cake board and decorate it with some berries.
8. Sprinkle some popping candy just before serving for that extra fizz!

I would suggest that you make the jelly and cake layers the day before, as it'll make the whole process more efficient. And I apologise for the lack of step by step pictures and a cross-section of the cake because it was a pretty hectic week and I had to enter the cake whole.
