This is a continuation of my last question.
the recipe I have is:
2 1/2 cups water
2 cups white sugar
3/4 cup brown sugar
1 moist vanilla bean, preferably Mexican or Bourbon (Madagascar)Combine the sugars and water in a saucepan.
Boil for at least 10 minutes.
Let cool. When solution has cooled, add the extract and stir well.
After I make my syrup, how long of a shelf life does it have? Do I need to refrigerate it, or can I keep it on my countertop?
