1/2 tsp Cinnamon
1/4 tsp Salt

1. In a large bowl with an electric mixer, cream together the butter and sugar until the mixture is light and fluffy. (5 minutes)
2. Add the eggs one at a time and combine well after each addition, scraping the bowl occasionally.
3. Into a bowl, sift together 3 cups of flour, allspice, cloves, cinnamon, and salt.
4. In another bowl, combine the buttermilk and baking soda.
5. Add the flour mixture to the butter mixture in batches alternating with the buttermilk mixture, ending with the flour.
6. In a bowl, toss together the raisins, walnuts, and 1 T flour. Stir the mixture into the batter with the jam, stirring until well combined.

8. Pour the batter into the pans and bake in the middle of a preheated 325F oven for 40 minutes or until a tester comes out clean.
