Got a loaf of this @ Greenfield Village. Ridiculously delicious. And it's actually baked in cans, which is fantastic.
2 cups raisins
1 1/2 cups boiling water
4 teaspoons baking soda
4 teaspoons butter, softened
1/2 cup granulated sugar
1/2 cup brown sugar
1 teaspoon salt
1 teaspoon vanilla
1 3/4 cups walnuts
4 cups flour
Pour boiling water over raisins; let cool. Stir in soda and other ingredients.
Fill 6 or 7 greased and floured large soup cans to half full.
Bake at 350 degrees for 45 minutes to an hour. Cool and remove from cans.
Makes 6 or 7 large loaves or 24 servings.
