Homemade Chocolate Syrup

I found this recipe here. I told my mom about it and she told me My Grandma Robbins used to make Chocolate syrup this way all the time. But I will add that is recipe is by far better then Hershey's version.

1 1/2 cups sugar
3/4 cup baking cocoa
1 cup water
1/4 teaspoon salt
1 teaspoon vanilla.

1. In a small saucepan, mix sugar cocoa and salt. 
2. Whisk  in the water. 
3. Bring to a boil stirring occasionally. 
4. Reduce heat and cook 1 minute. 
5. Remove from heat and add the vanilla. 
6. Cool store in fridge. So easy.
7. Store in a pint canning jar. An old Hershey container will work too.
