RHUBARB, VANILLA AND ANISE UPSIDE-DOWN CAKE

“Inherently sharp, rhubarb is one of my favourite ingredients, for its pleasing ability to temper sweetness. As the top layer in this upside-down cake, it not only excels in this role but its pretty pink colour makes for a beautiful presentation.You don’t have to make this ‘parquetry’ design but it’s simpler than it looks and allows you to cut the cake into satisfyingly neat squares”
