I really don't know if this is Irish or not but it's good. It's easy and cheap to make.

Heat oven to 325.

2 Tablespoons butter melted
1.5 cups buttermilk
2 eggs
3.5 cups flour
3/4 cup sugar
1 teaspoon salt
1 teaspoon soda
1 teaspoon caraway seed * I don't use this
1 cup raisins

Spray a 2.5 cup casserole with non stick or baking spray or grease as in the old way. Combine butter, buttermilk and eggs. In another bowl combine dry ingredients. Make a well in the center and add the milk eggs and butter mixture. Stir until the mixture is all moistened and add raisins. Put in prepared casserole and bake for 1 to 1 1/4 hours until knife in center comes out clean. Truth be told, I beat the first stuff, add the dry stuff to it with the mixer and then stir in the raisins.
