In a medium saucepan over medium heat, stir together sugar and water until dissolved. Then remove from heat. Let cool completely.
Transfer to a glass jar and seal tightly with a lid. Store in the refrigerator for up to 1 month.
Notes
Sugar swaps: You can use other kinds of sugar such as Demerara, raw cane sugar and brown sugar.Rich syrup: This recipe makes a simple syrup with a 1:1 ratio of sugar to water. For a thicker, sweeter syrup, try a 2:1 ratio of sugar to water. Flavor infusions: You can also add infusions such as mint, basil, cinnamon, vanilla, citrus zest — the pantry is your oyster here! It is better to heat the infusion agent with just water, letting it simmer down by half — so start with twice as much water. Once reduced, strain out the solids, then stir in the sugar while it's still warm. Ideally, measure the water, then add the exact same amount of sugar for a 1:1 ratio or twice as much for a 2:1 ratio.
