Step 1

1)Preheat the oven to 180C fan (200C/gas 6). Grease and line a loaf tin 11cm x 21cm, and set aside.

Step 2

2)Place the butter, sugar, lemon zest, 1 tablespoon of lemon juice and vanilla in the bowl of a free-standing food mixer with the paddle attachment in place. Beat on a high speed for 3-4 minutes, until light, then lower the speed to medium. Add the eggs, in small additions, scraping down the sides of the bowl. The mix may split a little, but don’t worry: it’ll come back together.

Step 3

3)Add the flour, salt and almonds in three additions.

Step 4

4)Finally, fold in 150g of blueberries, by hand, and pour into the prepared loaf tin.

Step 5

5)Bake for 15 minutes, then sprinkle the remaining 50g of blueberries over the top of the cake. Return to the oven for another 15 minutes, until the cake is golden-brown but still uncooked. Cover loosely with tinfoil and continue to bake for 25-30 minutes, until risen and cooked. Test by inserting a knife into the middle: it’s ready if it comes out clean. Remove from the oven and set aside, in its tin, to cool for 10 minutes, then remove from the tin and place on a wire rack to cool completely.

Step 6

6)Meanwhile, make the icing. Put the remaining tablespoon of lemon juice into a bowl with the icing sugar and whisk until smooth. Pour over the cake and gently spread out: the blueberries on the top of the cake will bleed into the icing a little, but don’t worry, this will add to the look.Enjoy !!
