Step 1

Preheat oven to 180°C. Line base and sides of a 7cm-deep, 10.5cm x 20.5cm (base) loaf pan with baking paper, allowing a 2cm overhang at both long ends.

Step 2

Using electric beaters, cream butter, sugar and lemon rind on high speed until pale and creamy. Add egg yolks, 1 at a time, beating well after each addition. Combine yoghurt and milk in a jug. Fold flour, almond meal and yoghurt mixture, 1 at a time, into butter mixture.

Step 3

Using electric beaters, beat eggwhites in a bowl until soft peaks form. Stir one-quarter of the eggwhites into batter. Gently fold in remaining eggwhites. Spoon into prepared pan. Bake for 45 minutes. Reduce oven to 160°C and bake for a further 15 to 20 minutes or until a skewer inserted into the centre comes out clean. Cool loaf in pan for 10 minutes. Lift onto a wire rack to cool completely.

Step 4

Make lemon icing: Combine icing sugar, 2 tablespoons lemon juice and butter in a bowl. Beat with a wooden spoon until smooth. Drizzle lemon icing over loaf. Sprinkle with lemon rind and serve.
