How to make
Break the eggs, add the yoghurt and stir. Add the softened lard, oil, sugar, baking soda and lemon zest.
Stir and add the flour in lots until you've kneaded a soft dough. If it's not enough, add a little more.
Tear balls from the dough and shape the cookies.
Dip each in sugar and arrange them in a tray laid out with baking paper, with the sugary side facing up.
Bake in a preheated 390°F (200 °C) oven until reddened.
