The best naturally gluten-free cookies you can get!
Preheat the oven to 165°C/325°F and line two baking sheets with parchment paper.
In a large bowl, with a wooden spoon, combine the flour, salt and sugar. Stir in the almond extract, vanilla and egg whites until the mixture is well combined. If the mixture is too dry, add a tablespoon of water.
Shape the cookie dough into 30 x 2.5cm (1in) balls. Roll each ball in the icing sugar and place on the prepared baking sheets with 5cm (2in) space between the cookies.
Bake for about 25 minutes, or until golden brown. The cookies will be chewy for the first day, and will become crispier by the second day, so plan accordingly based on your preference.
Store the cookies in an airtight container for up to a week.
