All my Polish cook books call for egg yolks too, so today I am sharing with you a five-ingredient recipe for shortbread cookies. I guess, a pinch of salt doesn't really count - it's "a pinch" :O)
And one more thing: these cookies are the best in their SIMPLE way.
What you see on my photos is a "holiday" version. Trust me, no toppings are needed :)
Recipe (makes 18-20 cookies):
1 1/2 cup flour,
1/2 cup powdered sugar,
150 g butter or margarine = 1 stick + 4 Tbsp,
pinch of salt,
vanilla sugar (1 packet=16 g).
*If you wish to give your cookies a different flavor, you can add 1-2 tsp cocoa or 1-2 tsp cinnamon or grinded nuts - choice is yours.
*Make sure to use cold butter and eggs.
