Q. Which is the sugar cube?

Answer

Sugar cubes, or sugar in a block form, are a common way to sweeten beverages. Crystallized sugar was developed for use in the more temperate regions of Europe. About 175 years ago, a Swiss man named Jakob Christoph Rad invented them while working as the manager of a sugar beet plant in what is now the Czech Republic. Sugar was manufactured in massive bricks that required grating or chopping before use. Jaggery, a softer and crumblier kind of sugar, was still used by many Indians. Tea and coffee were often sweetened during the period, especially at Irani restaurants. Even when sugar wasn't in limited supply, the business owners wouldn't risk losing clients by leaving it out on the table.
