What is a major disadvantage of the muffin mixing method?

The correct answer emphasizes that a major disadvantage of the muffin mixing method is the potential for toughness caused by over mixing. This method typically involves combining dry and wet ingredients separately and then mixing them together quickly. The goal is to incorporate the ingredients without developing gluten too much, which can lead to a tough texture.

If the batter is mixed too long, gluten development occurs to a greater extent, resulting in dense and chewy muffins instead of the desirable light and tender crumb. Therefore, it's crucial to mix only until the ingredients are just combined, leaving some lumps. This limitation highlights the importance of technique in achieving the perfect muffin texture, as over mixing can compromise the final product significantly.

Understanding this can help bakers master the muffin method, ensuring their creations are fluffy and enjoyable.
