โญ Buttermilk (Best Nut-Free Option)
1 cup buttermilk per 1 cup whole milkButtermilk works well because its acidity reacts with baking soda or baking powder to produce carbon dioxide, improving muffin rise and crumb structure. It also contains fat and proteins similar to whole milk, maintaining moisture and richness.
For best results, reduce any additional acidic ingredients slightly to balance flavors. Ensure buttermilk is well mixed before use.
Compared to whole milk, buttermilk produces muffins with a slightly tangier flavor and a tender, moist crumb, often considered an improvement in texture and taste.
