- Wash calamondins and slice in half crosswise. Remove seeds. Place calamondins (pulp and peel) in a blender or food processor and puree; you should have about 1 cup puree.
- Preheat oven to 350 degrees. Place puree in large mixing bowl and add walnuts, sugar, eggs, milk, oil, and salt. Mix with a hand mixer until well blended. Add remaining ingredients and mix about 1 minute (mixer will chop up raisins).
- Pour batter into a greased 9x5x3-inch loaf pan and bake for about 1 hour and 15 minutes. Bread is done when a toothpick inserted into the loaf can be removed with no batter clinging to it. Cool bread in the pan about 10 minutes, then turn it out onto a rack to finish cool.
