1/4 cup plain yogurt or sour cream
1/4 cup good quality olive oil
Zest and juice of 1 lemon
1/2 cup white rice flour
1/4 cup tapioca flour
1/2 cup sugar
1 tsp baking powder
Preheat oven to 350 degrees
First combine the yogurt and olive oil well. Stir in the egg, then the lemon juice and zest, to make a coherent mixture.
Next, combine all the dry ingredients together. Slowly add the wet ingredients into the dry. The dough will be sticky like and might stick all over your fingers.
Form small balls with the sticky dough and roll each ball into sugar. This will make the finished cookies crunchy and shimmery. Place on a baking sheet covered with a Silpat or layer of parchment paper.
Cook for around 12 minutes. The cookies will be soft at this point, but they will fill fully formed. Let them sit on a baking sheet to cool for about 5 minutes.
Carefully move the cookies to a cooling rack and let cool for another 5 minutes. Dig in and enjoy yourself!
