Chirstmas Baking: Shortbread

image from here

What's Christmas with out shortbread? This is my gluten free version I adapted from a Jamie Oliver recipe. It's super buttery and super crumbly, make it once and you'll realise why its called the best shortbread in the world.

The best (gluten free) shortbread in the world
250g best (pref. organic) unsalted butter
3x(125g) of gluten free flour (I use one part rice flour, one part gluten free plain flour and one part corn flour to make up 375g of flour)
100g organic golden caster sugar
optional flavours: zest of one lemon, 2 crumpled dried lavender flowers, vanilla essence

Cream together butter and sugar then add flavouring if using. Add in flour and mix together with a spoon till well combined. Press dough into a baking tray and prick all over with a fork. Bake at 170C until golden on top (about an hour). Cut into fingers while still warm.
