Combine:
1 cup boiling coffee
1 cup chopped dates
1 teaspoon soda
Let coffee, soda, and dates soak while mixing:
1 cup sugar
1 tablespoon butter
1 egg
1-1/2 cups flour
pinch of salt
1 cup chopped walnuts
1 teaspoon vanilla
Add date mixture to batter and mix well. Turn into a greased 4-1/2×8-inch loaf pan or 3 mini-loaves and bake at 300 degrees F until a toothpick comes out clean, about 1-1/2 hours (45 minutes for mini-loaves).
