This is the liquid stevia that I use in all of my recipes. Usually I call it "Stevia Working Solution" just to keep it distinct from commercially available liquid stevia extracts, which vary a lot from brand to brand in sweetening power. If making my other recipes that call for liquid stevia, I strongly recommend using this recipe.

Stevia Working Solution

 

Ingredients ratio:

• 1 part pure white stevia extract powder (no fillers)
• 9 parts water

Directions:

1. Measure stevia extract powder into a glass measuring cup.
2. Boil water.
3. Remove from heat and slowly pour correct amount of water over the stevia extract powder, using a whisk to stir so that all of the powder dissolves properly.
4. Pour into your desired airtight containers. I recommend glass dropper bottles. If you're worried about the heat causing damage to the container, let cool a bit first.
5. Store in refrigerator.

Notes:

• The ratio of stevia : water is based on volume, not weight. You may use teaspoons, tablespoons, cups---whatever you like. The batch size will change accordingly. Just be sure to make the batch small enough to keep in the refrigerator and use up within a month or so. I'm not sure exactly how long this stuff lasts, but it definitely lasts longer in the fridge than sitting out on the counter. If you start seeing particles or fuzzy stuff floating in your bottles of stevia solution, it has probably started growing stuff and should be discarded.
• Mixing the stevia extract powder and water in a bottle is not recommended. In my experience, that tends to leave particles or blobs of undissolved stevia, which taste terrible and make the rest of the solution less sweet than it should be for the quantities specified in my recipes. For best results, mix the solution in a separate bowl/measuring cup and then pour it into your dropper bottles.
• If you store other things in the same type of bottle, you will want to label the bottles.
