Amanda Faber usually would make a petit four over a few days but in the "Patisserie Week" Signature bake challenge she must bake them within hours. She imagines a tea party with her daughter and the types of cake she would enjoy which inspires her "Patisserie Week" Signature bake, a Lemon Sponge Cake with Cucumber Soak and Elderflower Buttercream.
