[1] [2] It differs from regular table sugar by having larger crystals. This helps keep the sugar suspended in preserves while cooking, preventing burning at the bottom of the pot.
Because curing increases the solute concentration in the food and hence decreases its water potential, the food becomes inhospitable for the microbe growth that causes food spoilage. Curing can be traced back to antiquity , and was the primary method of preserving meat and fish until the late 19th century.
