Blackberry Jam Crumble Tart

You might have to be quick to catch the last of the blackberries this year, but there are still some around. I think they came early this year, but while it is still 18 degrees outside I kind of forgot it was meant to be autumn...

I've been climbing around in bushes in the Ouseburn to gather what I can. I've made a little stock of jam, which is delicious with some toast in Cook House of a morning, but I also discovered a blackberry jam tart with a crumble topping...

It came about by accident as I needed something sweet for the menu at Cook House but had run out of eggs, cakes without eggs wasn't filling me with ideas or inspiration. A simple jam tart seemed the answer, then came the thought of crumble... it's so good... Unfortunately it uses a whole jar of jam each time I make one, so I'll have to get back out and find some more blackberries...

For the jam I started with a small batch, so you can scale up if you have more. These amounts made one large jar of jam. Take 300g of blackberries and wash them thoroughly, I came across some of the biggest spiders I've ever seen picking these guys... Put them in a pan with 20ml of water, 1 tablespoon of lemon juice and a piece of lemon rind and simmer very gently for 15 minutes until the fruit is really soft. Then add 300g of caster sugar, dissolve it slowly, then turn up the heat and boil for about 10 minutes, until it reaches 105°C. Turn off the heat and let it sit for 10 minutes, then fill sterilised jars and label.

For the tart I made a small batch of shortcrust pastry, 125g of plain flour, 55g of cold butter cubed, blitzed in the food processor to a fine crumb, then drizzle in a tiny amount of very cold water until it comes together. It often turns out better if you make double this amount however, then you get two tarts for your money, or you can freeze or refridgerate the other half...

Roll the pastry out and line a shallow tart tin, then spread a thin layer of the jam over the base of the pastry. To make the crumble topping melt 60g of butter in a pan, then add 5 tablespoons of oats, 4 tablespoons of caster sugar, 5 tablespoons of self raising flour and 2 tablespoons of ground almonds. Mix with a fork until you get a crumbly mix then sprinkle over the top of the jam.

 

Finally bake the lovely tart at 200°C for 15-20 minutes. It is a delicious autumnal jam tart that has me constantly making more jam so I can eat it again at the moment...
