2 tablespoons butter or margarine

1/2 pound grated Swiss or Gouda cheese

1 tablespoon flour

3 eggs

1 cup heavy cream

NOTE 1: All ingredients should be very cold.

DOUGH: Cut butter into flour and salt until it resembles very coarse meal. Stir in soda. Knead just to combine. Wrap in film and refrigerate 1 hour.

On a floured board roll out dough, fold in 3's, as if you were folding a letter. Chill 1 hour.

FILLING: Cook onions in butter until translucent. Let cool. Stir flour into cheese. Blend eggs, cream and seasonings.

Roll out dough and place in a quiche pan. Spread onions in the bottom. Spread cheese mixture and pour cream and eggs on top.
