I'm making a simple syrup with equal parts sugar and water in a glass measuring cup and want to avoid dirtying two measuring cups.
I want to measure one (say standard table sugar,) then add the water. What should the resulting volume of both be?
My experiment with table sugar, pouring 1/2 cup of table sugar into a glass container then pouring in 1/2 cup of water on top without stirring resulted in the water line reaching the 3/4 cup mark after a few seconds of absorption.
So the ratio of the volume of separated sugar and water to the mixture is 3:4.
I've been making hummingbird sugar water for years. Dissolving 2 Cups (16 dry oz) granulated sugar into 2 cups water makes about 25 oz (3-1/8 cups) of sugar-water. The sugar adds about 9/16 of it's dry volume to the liquid solute. Once I have this mix I add more water to make 48oz of sugar-water for the hummers. Sugar content is then a bit less than 19% sugar by volume.
