Put enough fresh or dried stevia leaf in the jar to fill it 2/3 full.
Pour alcohol of choice over the leaves to fill the jar and put the lid on tightly.
Put in a place where you will see it and let it sit for 36 hours, shaking occasionally.
Strain the liquid into a small saucepan.
Turn the heat on low and bring to a simmer. Do not boil! It will ruin the taste!!!
Simmer for about 30 minutes, stirring constantly and making sure not to boil. It will thicken. When it gets to your desired thickness, remove from heat.
Store in small jar in the refrigerator for up to 3 months.
Notes
Stevia can be grown outside in a garden or in a pot on a sunny window sill.
