i've been wanting to make these for a while now. and now that i finally have my new scale i could. they were very simple and easy to make and really yummy. here's the recipe...

...recipe from How to Be a Domestic Goddess
125 grams butter, softened
175 grams sugar
2 large eggs
zest of 1 lime
175 grams self-raising flour
pinch of salt
4 tablespoons milk

for the syrup
4 tablespoons lime juice (1-2 limes)
zest for decoration
100 grams icing sugar

Preheat oven to 180C/375 F.

Cream together butter and sugar. Add the eggs and lime zest, beating them well. Fold in the flour and salt and then the milk. Spoon into a well greased mini-loaf pan, and cook for about 25 minutes.

While the cakes are cooking make the syrup. Mix together the sugar and the lime juice.

As soon as the sponges are cooked take them out of the oven and prick with a cake tester all over. Spoon the syrup over the cakes to saturate. Let cool a little bit in the pan and then remove. If you leave them too long in the pan they will be difficult to remove. Top with a little bit of lime zest to decorate.
