Spray the pan well.Do not be skimpy when spraying the muffin pan. If you don’t have enough cooking spray or muffin liners you can use oil to grease the pan. The muffins will stick if you do not do a good job greasing your pan.
Use buttermilk or make your own.The buttermilk has a mild acidic quality to it which is important in this recipe. However, if you don’t have any buttermilk, you can easily make your own by adding one tablespoon of lemon juice or white vinegar to every one cup of milk and then letting it sit for about 5 minutes to curdle a bit.
Use fresh blueberries.For the best flavor use fresh blueberries if they are in season. Yes, you can use frozen, but fresh blueberries are always better.
