How sweet your strawberries are will make a difference in how much stevia you need to use. Start low, and creep up until it’s just right (it’s easy to overdo stevia, as it’s so concentrated!). I used my Blendtec to blend this, if you find it too pulpy, or seed-y when using a regular blender, you can always pour through a fine sieve before adding the 5 cups of water.
12 ounces strawberries (if frozen, defrosted), about 15 large strawberries, stemmed if fresh
2 cups of water
¾ cup freshly squeezed lemon juice
5 cups of water
30-50 drops liquid stevia
Combine the strawberries, 2 cups of water, and lemon juice in a blender. Blend until very smooth.
Add the five cups of water, and then sweeten to taste with the liquid stevia, starting low and working up, stirring well before taste-testing. Serve chilled or over ice.
