Fairtrade white chocolate, burnt butter and Brazil nut cookies

Preheat the oven to 150C. Sift together the flour, baking soda and salt. Melt the butter in a saucepan and heat, stirring continuously until brown bits begin to form at the bottom of the pan (approx 5 mins). Beat the melted butter together with the light brown sugar and granulated sugar until smooth. Add the egg, egg yolk and vanilla essence and beat to incorporate into sugar/butter mixture. Set the mixer to a low speed and gradually add the sifted dry ingredients. Add lemon zest, nutmeg, chocolate and Brazil nuts to taste. Roll dough into 2 inch diameter balls and lay on a lined baking sheet, aprox 2 inches apart. Bake in the preheated oven for 15 minutes or until brown around the edges and soft in the centre.
