In a medium saucepan, combine the granulated sugar and water.

Place the saucepan over medium heat. Stir occasionally until the sugar completely dissolves, which usually takes about 5 minutes.

Once the sugar is dissolved, remove the saucepan from heat. Stir in the vanilla extract.

Add the salt to the mixture.

Return the saucepan to low heat and let it simmer for 5-10 minutes until desired thickness is reached.

Once thickened, remove from heat and let it cool in the saucepan.

After cooling, pour the syrup into a clean jar or bottle.

Seal the container tightly and store it in the refrigerator.
