Blend cream and sugar well. Add eggs, butter, brandy, salt, cardamom and 2 cups of the flour, mixing well. Add enough more flour to make a stiff dough. Chill one hour.
Heat oil to a depth of 3 inches in a deep pan to a temperature of 365 degrees.
On a lightly floured canvas or board roll half of the dough paper-thin. Cut into diamond shapes 3 inches long, making a slit in the center of each. Pull one corner through the slit. Cook in the hot fat until a delicate brown. Dust with powdered sugar. Roll out remaining dough and proceed as above.
