Chocolate Syrup

Yesterday i made some chocolate syrup from scratch. Found the recipe online and i tried it this morning I loved it!!!
This is what i used:
1 1/2 cup sugar
3/4 cup coco
1 cup water
pinch of salt
1tsp vanilla
1 old cleaned out ketchup bottle

Brought sugar, coco, and water to boil added salt then boiled for 1 to 2 min and took off heat mixed in vanilla and let cool. Than i put it in the ketchup bottle to refrigerate and tried it this morning. I love it was great seemed like i didn't need to use as much as the store brand.
