Deep Dark Old Recipe Bran Muffins

Preheat an oven to 350 degrees F (175 degrees C). Grease 18 muffin cups, or line with paper muffin liners. Whisk the bran, flour, salt, and baking soda in a mixing bowl; set aside.

Beat the eggs in a mixing bowl. Whisk in the buttermilk, sugar, molasses, and melted shortening until smooth. Stir in the bran mixture along with the raisins until no dry lumps remain. Pour into the prepared muffin tins, filling them no more than 2/3 full.

Bake in the preheated oven until a toothpick inserted into the center comes out clean, about 20 minutes. Cool in the pans for 10 minutes before removing to cool completely on a wire rack.
