Stir together until sugar is dissolved
Let cool
Slice or snap corn on the cob into smaller chunks. (I snapped mine into thirds. I cut part way through the cob till I hit the center and then just snapped at the precut line)
Bring medium sized sauce pan with the water and corn to a boil
Reduce heat to medium and let simmer 30 min. or until water is reduced by half.
Pull out your corn cobs from the pan, or using a large strainer spoon(you know the ones with the holes in it!)
Strain out all of your corn from the pan
Add sugar, salt and vanilla to the pan, stir until sugar is dissolved
Using a candy thermometer, cook to soft ball stage stirring occasionally.
Remove from heat and let cool until ready to use
Store in refrigerator (it will keep for a long time!)
When ready to use, if you have a few sugar crystals, microwave it with just a little bit of water to gently melt sugar crystals before using
