Bananas and lime work well together in general evoking tropical flavors. This cake is actually from the UK, from a volume given to me in a cookbook swap. After GEMA's disappointing review, I made this myself and made some minor changes (namely reducing the flour by two tablespoons and adding a tablespoon of yogurt) and clarifying the directions according to preparation in my own kitchen. I found the cake to be a lovely snacking cake perfect as a midday sweet or informal dessert. As a low-fat chef, I was pleased to find the cake had a natural moistness drawn from the bananas, yogurt and raisins.
