For an extra layer of flavor, consider adding 1/2 cup of chopped pecans or walnuts to the batter. If you don't have orange zest on hand, a teaspoon of orange extract will also work well. To ensure the bread is fully cooked, check the internal temperature with a food thermometer. It should reach 200-205°F (93-96°C). Store leftover bread in an airtight container at room temperature for up to 3 days, or in the refrigerator for up to a week. For a richer flavor, use melted butter instead of vegetable oil.
