Lemon And Blackcurrant Stripe Cake
It starts its life, simply, as a flat sponge cake in a baking sheet. Rolled up and covered in silky buttercream, it looks rather like a barrel. Cut into it, however — revealing the stripes! — and it looks like a whole lot of vertically inclined (and very colourful) fun. - Yotam Ottolenghi & Helen Goh, Sweet.
