Final answer:
Sugar should weigh the same as flour in a recipe like a classic pound cake where ingredients are measured by weight. However, sugar is denser than flour, so they might not weigh the same by volume. Using a scale is important for precision in baking.
Step-by-step explanation:
The question of whether sugar should weigh the same or slightly more than the flour is not a true or false question as it depends on the recipe being used. For example, in the context of a classic pound cake recipe, the weight of sugar would be equal to the weight of the flour, as each ingredient is used in equal pound measurements. If a recipe calls for a balance in weight between sugar and flour, then they should indeed weigh the same. However, in terms of density, sugar and flour may not weigh the same when measured by volume because sugar is denser than flour. Therefore, using a scale to precisely measure the weight of these ingredients is crucial in baking to maintain the right proportions.
