Put berries in a small saucepan.
Add sugar (or sweetener) and lemon juice. Cook on high just until the mixture starts
boil. Reduce heat to medium and mash the berries with a spatula, stirring frequently
keep from burning or sticking to the bottom of the pan.
After about 15 minutes, most of the
liquid should be cooked off. When you reach your desired consistency, let it cool
pour into a container to refrigerate for up to 1 week.
