Notes
Lemon: Fresh lemons add a vibrant, natural flavor that bottled juice can't match. For the best taste, always opt for fresh lemons.
Buttermilk Substitute: If you don't have buttermilk on hand, mix 1.5 tablespoons of vinegar or lemon juice with 1.5 cups of whole milk. Let it sit for 15 minutes before using.
Mixing: To ensure even mixing, scrape down the sides of the bowl throughout the process. This prevents uneven batter and improves the final texture.
Measuring Ingredients: For precise results, use a kitchen scale to weigh your ingredients. When using measuring cups, ensure that each ingredient is leveled off for accurate measurement.
