Preheat your oven to 350°F/176°C. Grease and lightly flour two 9x5-inch loaf pans. In a large bowl, combine the flour, baking soda, nutmeg, and salt. Stir together until evenly mixed.
In another bowl, whisk together the sugar and persimmon puree until combined. Stir in the chopped pecans, melted butter, eggs, and cognac until well blended. Pour the wet ingredients into the dry ingredients and mix until just combined.
Fold in the raisins. Be careful not to over-mix. Divide the batter evenly between the two prepared loaf pans and smooth out the top to look even. Bake in the preheated oven for 40-45 minutes, or until a toothpick inserted into the center comes out clean.
Allow the loaves to cool in the pans for 10 minutes before turning them out onto wire racks to cool completely.
