lemon pound cake

The sugar is definitely higher than flour. Your given ratio between the flour and sugar is 100/145. that is already an extreme for a cake to be considered in the pound cake category ( even with high ratio .classification). It will be coyly sweet. Another thing is if tt will contains some lemon juice that will further invert the sugar making the cake more sweeter. But normally such lemon pound cake is made with grated lemon peel as flavoring. It should be only up to 125% sugar to 100 flour maximum( for your quantities that will be only up to 7.5 ounces.) for that amount of flour. Meanwhile the classical pound cake ( low ratio) has an equivalent amount of flour and sugar in weight for weight basis. I was thinking that the flour in your recipe was calculated based on the unsifted status of 120 grams per cu; then calculating the sugar it will amount to 138% in relation to flour. Still a high for a lemon pound cake. Roy Roy

You're trying to make volume and weight equal. Since sugar is denser than flour, a higher weight of sugar could very well be less in volume than an amount of flour that weighs less, up to a certain point. For example, you have a cup of flour and a cup of sugar. The sugar is going to weigh more because of its density. On the flip side, if you have six ounces of sugar and six ounces of flour, there is going to be less sugar than flour because of its density. HTH Peggy

We're talking weight, here, not the amount.

The weight of different things varies. An equal volume of one thing, say 1 cup, will weigh differently than another. As in flour and sugar, above.

If you lined up separate cups of, say, flour, sugar, salt, water, and butter, and weighed them, they would all weigh different amounts.

The only reason some recipes call for weight instead of amount (volume) is that the weight may be more consistent than the volume. For example, flour right out of the bag is compressed, and a cup would contain more than after you sift it and "un-pack" it -- then a cup weighs less.

So, 6 oz. of cake flour could be different amounts depending on whether it was sifter, or not. It doesn't matter if it is packed tight, as long as you weigh it and use 6 oz.

That's a more accurate way to measure flour, and in a recipe, a cup of sifted flour is definitely LESS flour than a cup of packed flour!

You aren't accounting for density. A cup of marshmallows weighs less than a cup of butter. You can search the USDA database and get some examples of what various food substances weigh. They generally have the weight for one cup of a given food.
