In a large bowl, beat eggs, sugar, buttermilk, mayonnaise and vanilla extract until smooth. In another bowl, mix flour, salt, baking powder, baking soda and cinnamon. Add to egg mixture and stir just until combined.
Core apples and chop. Add to batter with raisins and nuts; stir just to mix. Spread batter evenly in 2 greased and floured 9x5-inch loaf pans. Bake at 375° F until a slender wooden pick inserted in the center comes out clean, about 1 hour and 10 minutes.
Let bread cool in pans on a rack for 10 minutes, then turn out onto a rack to cool completely.
Servings: 2 loaves, 1 3/4 pounds each
