Preheat the oven to 350 degrees Fahrenheit or 180 degrees Celsius.

On a cookie tray, spread a baking sheet or parchment paper.

Mix all-purpose flour, baking soda, salt, and ground cardamom in a small bowl using a small wire whisk.

If the sugar granules are big, powder them using your food processor or mixer-grinder. In a large mixing bowl, mix together softened butter and sugar.

Cream the butter and sugar till you cannot feel the sugar granules in the mixture. The time for this step depends on the size of the sugar granules.

Add the flour mixture to the butter-sugar mix.

Combine the flour mixture and the butter mixture using your hands to form a soft dough.

Make 20 balls out of the dough, each about 1 inch in diameter. Slightly flatten with your palm. Place the balls on the cookie sheet about 1.5 to 2 inches apart.

Bake the cookies for about 10-12 minutes. When they come out of the oven they will be a little soft, but will harden on cooling.

Cool on a wire rack.

Store in an air-tight cookie jar.
