Hawaij is a Yemeni warm spice blend that's heavy on the cardamom and can be used to flavor baked goods, frosting or even sprinkled in coffee! You can make a substitute by mixing 1 tablespoon ground ginger, 1 tablespoon ground cardamom, 1/4 teaspoon ground nutmeg, 1/4 teaspoon ground cloves and 1/4 teaspoon ground cinnamon.
