Lemon Louise Slice
Cream the butter and sugar, then add the egg yolks.
Chuck in the lemon zest and then the flour and baking powder and mix until it's like bread crumbs.
Bake at 150C for 15 - 17 minutes depending on your oven.
Just pour and spread the curd till it covers the base evenly.
Beat the egg whites until they're nearly done then slowly add the sugar and keep beating until you get the 'stiff peaks' effect.
Fold in the coconut.
