Usually one pound of powdered sugar is in a box. Which is about 2 cups.
You will need 1 pound of powdered sugar to make a batch of cookies according to the recipe.
Yes, you can use powdered sugar in frosting instead of white sugar. In fact, powdered sugar is often preferred for frostings because it dissolves easily and creates a smooth texture. Just be aware that using powdered sugar will result in a sweeter frosting, so you may need to adjust the amount to suit your taste.
First, powdered sugar is not simply pulverized granulated sugar. There is cornstarch added to keep the extremely fine "regular" sugar from sticking together. Second, just from calorie count, one would need 50 - 75 percent more powdered sugar. Third, it tastes different. I know this from experience...ran out of granulated sugar...replaced it with powdered sugar...threw out my cup of tea! Finally, it's considerably more expensive. I would consider replacing powdered sugar with granulated--blend in blender until the consistency is correct and there is the amount you need. If it is being used in something that requires a bit of thickening, add small amounts of cornstarch until reaching the desired thickness. As a baker with over 35 years of experience, I would not substitute powdered for granulated sugar.
It depends on the powder. It is powdered sugar or powdered lead? One will be much much heavier than the other. You need to know the density of the powder to answer this question.
Cornstarch is added to confectioners (powdered) sugar to prevent the sugar from lumping, so the amount is quite minimal. And adding cornstarch to granulated sugar isn't what makes it confectioners sugar. Confectioners sugar is much finer and softer than granulated sugar, it has a texture much like that of cornstarch. So you would have to be able to grind granulated sugar into a very fine powder in order to make it like confectioners sugar.
do i need to sift icingsugar when baking lemon squares
You probably would need flour, sugar, water, milk, eggs, glaze (like on donuts), powdered sugar, and cream. I'm not sure how much of each though
1 box powdered coca 1 box powdered sugar so equal quantities of both.
Yes you can, but you'll have to use more because of its texture so use 2 cups powdered sugar for every 1 cup granulated sugar. Powder sugar is just granulated sugar that has been spun for a smoother texture. It is usually used for frostings or such.
To make white chocolate at home, you will need cocoa butter, powdered sugar, powdered milk, and vanilla extract. Melt the cocoa butter, then mix in the powdered sugar, powdered milk, and vanilla extract until smooth. Pour the mixture into molds and let it set in the refrigerator.
The sugar is the same, powdered is just processed to a finer crystal and I believe has cornstarch with it to keep it a powder. Cheaper brands of powdered sugar, also called icing sugar or confectioners' sugar, might have cornstarch, also called cornflour, added. Pure powdered sugar is available and the quality is far better without the added flour; you simply need to sieve it, but you need to do this with the cheap varieties anyway. If it hasn't been stored properly it might be in a hard block or blocks, but this is easily fixed by putting it, in its sealed bag, into a larger plastic bag for safety and then hitting it a bit with a rolling pin or something else heavy. Or you can put it in a food processor to break it up. Then sieve it before you measure it out.
Greg needs 1.25 kg of sugar more so that his amount of sugar will be exact
