Sweet syrup produced by breaking down (hydrolyzing) cornstarch (a product of corn). Corn syrup contains dextrins, maltose, and dextrose and is used in baked goods, jelly and jam, and candy. High-fructose corn syrup is widely used in the manufacture of soft drinks and other foods because it is considerably cheaper than sucrose.

In cooking, a syrup (from Arabic شراب sharab, beverage, via Latin siropus) is a thick, viscous liquid, containing a large amount of dissolved sugars, but showing little tendency to deposit crystals. The viscosity arises from the multiple hydrogen bonds between the dissolved sugar, which has many hydroxyl (OH) groups, and the water. Technically and scientifically, the term syrup is also employed to denote viscous, generally residual, liquids, containing substances other than sugars in solution. Artificial maple syrup is made with water and an extremely large amount of dissolved sugar. The solution is heated so more sugar can be put in than normally possible. The solution becomes super-saturated.
Flavoured syrups are made by adding flavouring matter to a simple syrup. For instance, syrupus aromaticus is prepared by adding certain quantities of orange flavouring and cinnamon water to simple syrup. Similarly, medicated syrups are prepared by adding medicaments to, or dissolving them in, the simple syrup.
Simple syrup is made by stirring granulated sugar into hot water in a sauce pan until the sugar is dissolved and then cooling the solution. Generally, a ratio of two parts sugar to one part water is used.
To make gomme syrup, bring sugar and water to a boil, then add gum powder dissolved in water. Strain for use.
