I love blueberries and they’re incredibly good for you. However, I haven’t really used them much in baking as although they look very pretty, I’ve found them to be rather tasteless when in a cake. I often experiment with mixing flavours and this week found a perfect partner for those dull blueberries (sorry!). Lime and blueberries work really well together, the lime enhances the blueberry flavour and together they make a scrumptious cake…
Zesty Lime and Blueberry Cake
This cake is a basic sponge (baked in two 8” tins) but with the zest of two limes added. A syrup is then made with the juice of one of the limes and two tablespoons of sugar to drizzle over the cake as soon as it comes out of the oven. (To make the syrup just stir together the juice and sugar in a pan over a medium heat until the sugar is dissolved. Bring to the boil, stirring, until the mixture starts to thicken.)
I made two fillings for the cake which really gave it all the flavour, a lime curd and a blueberry and lime conserve. They were both slathered in between the two sponge cake layers to make this a really heavenly, zesty cake. The flavours are very summery and would be perfect for a special Mother’s Day cake or for Easter. A few crystallised violets would be pretty on top or pile on some cream and fresh blueberries. Mine didn’t hang around enough to look pretty but I will be making it again so maybe next time I will make a bit more effort on the presentation.
Juice of 1 Lime
2 Eggs, well beaten
Place the butter, sugar and lime juice in a bowl over a pan of boiling water and continue to heat, stirring continuously to melt the butter and dissolve the sugar. Remove from the heat for a minute and then add the beaten eggs, stirring well. Put back on the heat, continuing to stir well until the mixture thickens. Leave to cool then it’s ready for use or can be stored in the fridge for a few days.
Blueberry and Lime Conserve
Juice of 1 Lime
4 tablespoons sugar
Place all the ingredients in a pan over a medium heat, stirring to dissolve the sugar and soften the fruit – about ten minutes. Mash the fruit down (I just used a potato masher) and bring to the boil. Leave the mixture to boil rapidly, stirring occasionally, until it thickens. It can be tested on a very cold saucer to see if it is set. I like mine fairly soft so that it spreads easily on the cake.
The whole thing is fiddly and high in sugar but it’s really worth the effort and try to just have a small piece!
