Blackberry Jam Crumble Shortbread

Blackberry shortbread crumbleCR2

I am new to shortbread and I was looking through my books and came upon this recipe there was no picture to go by so I decide to do my own.  I must say that the blackberry jam made it for me.

Blackberry Jam

Don’t you love it when you learn something new, I learnt about the ‘thread stage’, this jam needs to reach this stage and then you will know it is ready.  It is when you take your spoon out of the jam, making sure it is lightly coated.  Let it cool (don’t be too eager to tough it, it is quite hot), touch the jam with your forefinger then gently squeeze your forefinger and thumb together, when you pull them apart there should be a thread of jam between them and this is when your jam is ready.

Loosening the top of the shortbread will help the jam to stick.

I did my in a 20 x 20cm roasting tin as this is all I had but I do suggest a bigger one as suggested in the recipe below.

I have not tried a huge amount of recipes from this book – JOHN WHAITE BAKES AT HOME  but I do plan on trying some more as some of the recipes really make my mouth water.

You can of course by the jam and use that instead of making your own.
