Blue Mondays

I am not going to even begin to take credit for this. Lucy Young, protoge of the wonderful Mary Berry, is a great cook and recipe writer in her own right. Long established in the Aga community and beyond, she ensures all of her recipes cater to conventional ovens also; much to our benefit. This blueberry crumble cake is more of a blueberry-muffin-meets-shortbread than your standard cake. If you're anything like me, then you would think that is a good thing.

300g (10oz) self-raising flour

1 tsp baking powder (be sure to use just one measured tsp as if you use too much the cake will rise too much then cave in the center)

2 large eggs, beaten

Grated zest of 1 small lemon (if you are a thorough grater then you may only need half a lemon)

150g (5oz) unsalted butter, melted

200g (10oz) blueberries

For the crumble topping:

75g (3oz) self-raising flour

40g (1 1/2oz) unsalted butter, softened

75g (3oz) demerera sugar

25g (1oz) semolina (although this seems like very little, trust me it's worth adding)

You will need a deep, 20cm (8in) diameter spring form tin. Line the base with a disk of parchment and butter the sides well.

To make the cake, measure the flour, baking powder and caster sugar into a mixing bowl. Stir in the beaten eggs. Add the lemon zest and melted butter and beat again with a wooden spoon until combined. Although the recipe doesn't state it, I'm going to tell you: this is a very dry mix. It almost has the consistency of a very wet cookie or shortbread mixture so don't be alarmed if it doesn't resemble cake batter.

Spread two thirds of the mixture into the base of the tin (you may need to 'push' rather than 'spread') and scatter over the blueberries. Then spoon the rest of the mixture on top and try and leave a smooth, even surface. If there are the odd gaps, do not worry.

To make the crumble topping, mix together all the ingredients in a bowl and rub together with your fingertips to give a fine crumble mixture. Sprinkle this over the top of the cake (it will also serve to fill in any gaps that may be left showing the odd blueberry or two).

Bake in a preheated oven (160C /320 F for a fan oven) be sure not to have it too hot or the sides will go too crunchy and the center will stay gooey, too low and the whole cake will become rather hard. Bake for about 1 1/4 until golden brown and when the centre is tested with a skewer it comes out clean.

Remove from the tin and paper. Leave to cool slightly as the centre stays hot for some time, but try to serve warm. It is an amazing afternoon tea cake or post-lunch desert. I would serve it with pouring cream or cold vanilla custard.
