Raspberries
You would make raspberry preserve similar to the way you would make other types of berry reserves. In a medium-sized, pot combine two cups of raspberries, three cups of sugar, a teaspoon of vanilla, and two teaspoons of lemon juice and a third cup of water. Cook over medium heat for 30 minutes and let cool. Pour preserves into canning jars, seal the jars and place jars in a warm water bath for 20 minutes.
