Stevia has been used for centuries by the Guaraní people of Paraguay and Brazil and has recently gained popularity as a natural, zero-calorie sweetener that is not synthetically produced. It is most often added to beverages and desserts.
Crush a pinch of leaf into teas while steeping or use the leaves to make a sweetening syrup. Add one cup of warm water to 1/4 C finely crushed dried leaves. Put in an airtight jar and allow to steep for 24 hours. Strain and use, or cook on low heat, reducing to a concentrated syrup. The syrup should last for several years, if kept in an airtight container in your refrigerator.
