What you do is sift the flour into a roomy mixing bowl, lifting the sieve quite high to give the flour a good airing as it goes down, then simply add all the other ingredients.
Now, using an electric hand whisk, combine them for about 1 minute until you have a smooth creamy consistency.
Spoon the mixture into the prepared tin. Level off the surface with the back of a spoon, then sprinkle the demerara sugar and crushed almonds all over.
Bake on a lower shelf so that the top of the tin is aligned with the centre of the oven for about 1 hour 5 minutes, or until the cake is springy in the centre.
Cool in the tin for 10 minutes, then turn out onto a wire rack to cool.
I think that this cake tastes better after a day or two, so leave it in its liner and store in a tin.
Pre-heat the oven to 180°C, gas mark 4
You will also need a Delia Online Loaf Tin (or a standard 2lb loaf tin), lined with a 2lb traditional loaf tin liner
