Simple syrup, also known as sugar syrup or bar syrup, is a sweetener made of sugar and water. It is often used to sweeten cold beverages, in which solid sugar will not readily dissolve. As its name suggests, simple syrup is very easy to prepare. Prepared syrup can be refrigerated for up to a week. It is 30% sweeter than table sugar.
1 part water
1–2 parts granulated sugar
Combine the sugar and cold water in a saucepan.
Bring the water to a boil over high heat, stirring constantly.
When all of the sugar has dissolved, remove from the heat and allow to cool to room temperature. This should only take a few minutes.
Transfer to a storage container, and refrigerate until needed.
