Step 1

Add the almond meal, caster sugar and plain flour (if using) to the blender. Season with a little salt.

Step 2

Blend the ingredients until well combined. Pour the egg whites in a high cup and beat them for a minute or so until firm but not too stiff.

Step 3

Pour the dry almond mixture from the blender in a large mixing bowl and add the beaten egg whites.

Step 4

Stir well until you get a wet crumbly cookie dough. Add the amaretto (or bourbon) and the almond extract.

Step 5

Give the cookie dough one last firm stir. Now make little even balls from the sticky dough and place the balls on a baking tray lined with baking paper. Do this in batches if necessary.

Step 6

Then bake the cookies in a preheated oven at 300°F (150°C) for 25 to 30 minutes until glossy and firm. Remove the baked cookies from the oven and let them cool down fully at room temperature.
