What is White Sugar?

Sugar is sucrose- a solid crystalline sweetener found in plants like sugarcane and sugar beets. Sugar was obtained through sugarcane from ancient times. New Guinea is the origin of sugarcane, and from there, its production has spread to Asia, China, and other countries. The first sugar mill was established in 1508 in the western hemisphere.  The sweetness of sugar beet was recorded in 1590 AD.  The first sugar beet factory was established in 1802 in Silesia. Sugar is manufactured in more than 200 countries, of which most companies use sugar cane to produce sugar.

White sugar is pure sucrose without any additional additives, color or odour. The crystals of white sugar are larger in size and measurable. White granulated sugar is used in regular sweet drinks and desserts that do not require quick dissolution. White granulated sugar is boiled or stirred to dissolve, which takes longer than powdered sugar or caster sugar. 

The other names of white sugar are table sugar, granulated sugar, and regular sugar. White sugar does not contain moisture because of its larger granules. White sugar comes in various forms like regular granulated sugar, superfine sugar, fruit sugar, coarse sugar, baker’s special sugar, sanding sugar, and powdered sugar. Each of these types of sugar is obtained by crushing or pulverizing the white granulated sugar.

What is Caster Sugar?

Sugar cane is widely used across the world to make sugar. Sugar is produced by harvesting sugar cane plants, extracting juice, removing impurities, boiling, crystallizing, and then packaging. Caster sugar is one type of sugar obtained by crushing the white granulated sugar into smaller granules. These granules are easily dissolvable but hard to measure. Caster sugar is also termed superfine sugar and ultrafine sugar. Caster sugar is used by professional chefs in their kitchens to bake cakes, desserts, and other sweet dishes that require quick sugar soluble. 

Caster sugar gives text, flavor, and odor to sweet dishes without any additional colors. It is preferred over granulated sugar to bake dishes that are sprayed with sugar from the top. Caster sugar has more moisture than white sugar as the granules are small and easily get dissolved in the temperature. Caster sugar is also made at home by just grinding the regular sugar. It is used as a topping in desserts to add sweetness.
