CRUMB
Whisk together the flour and brown sugar. With your hands, or a pastry blender, combine the butter into the flour mixture until large clumps form. Refrain from eating the entire crumb topping.
BREAD
Place a rack in the upper third of the oven and preheat to 350 degrees F.
Grease a 9×4x3-inch loaf pan and set aside.
In a large bowl whisk together flour and salt.
In a small bowl, whisk together persimmon pulp and baking soda. This will thicken the pulp a bit.
In a medium bowl, whisk together sugar, oil, eggs, spices, and fresh ginger. Once well incorporated, whisk in the persimmon mixture. Pour the wet ingredients, all at once, into the dry ingredients. Fold to incorporate. Once no flour remains, pour into the loaf pan and place in the oven.
Bake at 350 for 30 minutes. Lower heat to 325, and bake for about another 25-35 minutes, or until a skewer inserted in the loaf comes out clean. Allow to cool in the pan for 15 minutes, then invert onto a cooling rack to cool to room temperature before serving. Loaf lasts well wrapped at room temperature for up to five days.
