I've been getting into classic cocktail making and just set out to compare the amount of sugar in various methods of sweetening: sugar cubes, granulated sugar, powdered sugar, 2:1 simple syrup and 1:1 simple syrup. Where I get confused is with powdered sugar.
Google says powder sugar has 2.5g sugar per tsp, while granulated has 4g per tsp. But if I take a cup of granulated sugar and blend it into powdered, I end up with a lowr volume at the end. So shouldn't a tsp of powdered sugar have more than 4g?
Can anyone confirm my google findings?
