Baking cookies is a great example. You weigh the ingredients for the dough to ensure accuracy, but then portion the dough into individual cookies using a scoop or by eye, relying on volume or count for consistent size.
In baking, weighing ingredients (using a kitchen scale) is generally more accurate than measuring by volume (using cups and spoons). This is because volume measurements can be inconsistent due to factors like how tightly packed the ingredient is. For example, a cup of flour can vary significantly in weight depending on whether it's spooned in lightly or scooped directly from the bag. Weighing eliminates this variability, leading to more consistent results in the final product.
However, once the dough or batter is made, portioning into individual servings is often done by volume or count for convenience and speed. For instance, when making cookies, you might weigh all the ingredients for the dough to ensure the correct ratios. Then, you would use a cookie scoop (which measures volume) to portion out the dough into individual cookies. Alternatively, you might divide the dough into a specific number of pieces (count) and then shape each piece into a cookie.
The combination of these two methods leverages the strengths of each. Weighing ensures accurate ingredient ratios for the overall recipe, while volume or count portioning provides a practical and efficient way to create uniform individual servings. This approach is common in many baking applications, including cookies, muffins, scones, and rolls.
Even when portioning by volume or count, periodically weigh a few portions to ensure consistency. This helps catch any drift in portion size and maintain uniformity across the entire batch.
