1. Preheat your oven to 350°F and line a muffin tin with paper liners or grease it well.
2. In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
3. In another bowl, mix the buttermilk, egg, melted butter, and vanilla extract until well combined.
4. Pour the wet ingredients into the dry ingredients and stir until just combined. Be careful not to overmix, as this can make the muffins tough.
5. Fold in the cooked and crumbled sausage.
6. Divide the batter evenly among the muffin cups, filling each about two-thirds full.
7. Bake in the preheated oven for 15-18 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
8. Allow to cool in the pan for a few minutes before transferring to a wire rack.

Growing up, I learned the importance of using fresh ingredients and trusting my senses while cooking. These steps reflect that spirit, encouraging you to engage with the process and enjoy the aroma of baking muffins that fill your kitchen.
