In a large cast iron skillet, gently melt one tablespoon of butter and swirl to coat the pan. 

Cut each biscuit into quarters and set aside.

In a small bowl, combine 1/2 cup sugar, the zest of one lemon, and 1/2 teaspoon ground cardamom. Stir to mix. 

Melt the remainder of the stick of butter in a large bowl. 

Dip each of the biscuit pieces into the melted butter and arrange in a single layer in the skillet. 

Sprinkle the sugar mixture over the top of the buttered biscuit pieces and then squeeze the juice of 1/2 lemon over the whole pan. 

Bake at 350 degrees for about 20 minutes, or until the biscuits are cooked and just golden. Enjoy.
