1. Butter (melted and cooled): Butter adds richness and moisture to the muffins, resulting in a tender crumb. It also contributes to the overall flavor. We use salted butter but if you use unsalted butter, just add a pinch more salt to the batter.
2. Flour: Flour provides structure to the muffins. It helps hold the other ingredients together and gives the muffins their texture.
3. Salt: Salt enhances the flavors in the muffins and balances the sweetness. It also helps strengthen the gluten structure in the flour.
4. Baking soda: Baking soda is a leavening agent that helps the muffins rise by producing carbon dioxide gas when combined with acidic ingredients like yogurt and orange juice.
5. Poppy seeds: Poppy seeds add texture and visual interest to the muffins. They also impart a subtle nutty flavor.
6. Eggs: Eggs act as a binding agent, helping to hold the muffins together. They also contribute to the structure and moisture of the muffins.
7. Plain Greek yogurt: Greek yogurt adds moisture and richness to the muffins while also providing a tangy flavor. It helps keep the muffins tender.
8. Vanilla extract: Vanilla extract enhances the overall flavor of the muffins and adds a warm, aromatic note.
9. Orange extract: Orange extract intensifies the orange flavor in the muffins, giving them a more pronounced citrus taste.
10. Orange zest: Orange zest provides a burst of fresh, citrusy flavor to the muffins. It adds brightness and aroma.
11. Fresh squeezed orange juice: Orange juice adds moisture and acidity to the muffins. It also enhances the orange flavor.
12. Sugar: Sugar sweetens the muffins and provides the necessary sweetness to balance the tartness of the orange flavor.
13. Coarse Sugar: Coarse sugar sprinkled on top of the muffins adds a crunchy texture and sweet flavor to the finished muffins.
14. Powdered sugar: Powdered sugar acts as a binding agent, helping to hold the glaze together and adhere to the surface of the muffins.

1. Navel Oranges: Navel oranges are widely available in many grocery stores and markets. They have a sweet, slightly tangy flavor and are easy to peel. Navel oranges are excellent for both juicing and using the zest to add citrusy brightness to muffin recipes.
2. Valencia Oranges: Valencia oranges are another common variety found in grocery stores. They are known for their juicy flesh and balanced sweetness. Valencia oranges are ideal for juicing, and their zest is  a great way to infuse muffins with citrus flavor.
3. Cara Cara Oranges:  Cara Cara oranges can often be found in larger supermarkets, especially during their peak season from December to April. They have a unique pinkish-red flesh and a sweet, slightly tangy flavor that adds a delightful twist to muffin recipes.
4. Mandarin Oranges (Clementines or Tangerines): Mandarins like Clementines or Tangerines are small, easy-to-peel oranges with a sweet, mild flavor. They’re typically available in the winter months and can add a refreshing citrus taste to muffins without being overpowering.
5. Regular Oranges: Sometimes, the simplest option is the best. Regular oranges, often labeled simply as “oranges” or “juice oranges,” are widely available year-round and can be used effectively in muffin recipes. These are good quality fresh fruits that will add flavor to the muffins.

When selecting oranges for muffin recipes, look for fruits that are firm, heavy for their size, and free from blemishes. Organic or locally grown oranges may offer even better flavor, as they’re often fresher and more flavorful than those that have been shipped long distances. Regardless of the variety you choose, using fresh oranges—both their juice and zest—will add bright, citrusy flavor to your muffins and elevate them to new heights of deliciousness.

How to keep Muffins fresh and delicious:

1. Cool Completely: Before storing your muffins, make sure they have cooled completely to room temperature. Placing warm muffins in a storage container can create condensation, leading to sogginess.
2. Use an Airtight Container: Transfer the cooled muffins to an airtight container. This could be a plastic storage container with a tight-fitting lid or a sealable plastic bag. Airtight containers help prevent moisture loss, which can dry out the muffins.
3. Line with Paper Towels: If you’re stacking multiple layers of muffins in the container, place a sheet of parchment paper or paper towels between the layers. This helps absorb any excess moisture and prevents the muffins from sticking together.
4. Store at Room Temperature: Orange Poppy Seed Muffins can be stored at room temperature for 2 to 3 days. However, if your kitchen is particularly warm or humid, it’s best to store them in the refrigerator to prolong freshness.
5. Refrigerate for Longer Shelf Life: If you want to extend the shelf life of your muffins, you can store them in the refrigerator. Place the airtight container in the fridge, and your muffins should stay fresh for up to 5 to 7 days. Just be aware that refrigeration can sometimes cause the muffins to become slightly denser.
6. Freeze for Longer Storage: For longer-term storage, you can freeze your Orange Poppy Seed Muffins. Wrap each muffin individually in plastic wrap or aluminum foil, then place them in a freezer-safe bag or container. Properly stored, the muffins can last in the freezer for up to 2 to 3 months. To thaw, simply leave them at room temperature or microwave them briefly until warmed through.

By following these storage tips, you can enjoy your Orange Poppy Seed Muffins at their best for days or even weeks after baking. Whether you’re savoring them one by one or saving them for later, these delicious muffins are sure to brighten your day with their citrusy goodness!
