Rainbow Roulade with Lime Cream Cheese Chantilly

It is good to have a repertoire of cake recipes for anniversaries and birthdays. This one is great for kids, but it also works for adults, especially if you tailor the cake to their favourite colours. There are many different types of food colouring to use – gel, fondant and liquid colouring. I like to use the gel or fondant ones as you need to use a lot of the liquid variety to get strong colours, and this can adjust the consistency of the mixture.
