Rosemary and Walnut Shortbread and Orange and Cardamom Shortbread

As promised here is another recipe I did today...

Rosemary and Walnut Shortbread

325g plain flour
200g salted butter
125g caster sugar
2 egg yolks
2 tsp rosemary , finely chopped
100g walnuts , chopped

Put the flour and butter in a food processor and whizz until the mixture looks like breadcrumbs. Add the sugar, egg yolks and rosemary and whizz to a dough. Tip onto a lightly floured work surface and knead in the walnuts. Shape into a log about 5cm across. Wrap in cling film and chill for an hour.
Heat the oven to 180C/fan 160/gas 4. Slice the dough into biscuits and arrange on a lined baking sheet. Bake for 20 minutes then cool.

To do the Orange and Cardamom, replace the rosemary and walnuts with the zest of one orange and 5 cardamom pod seeds crushed in a pestle and mortar.
