Add frozen peaches, lemon juice, water, and liquid stevia to a pot on the stove. Simmer the ingredients with a lid on the pot until the peaches are soft enough to mash with a fork. Depending on how large your pieces of frozen peaches are, the cooking time may vary.
Step 2
Once the peaches are soft, pour all the ingredients into a blender or bullet blender. Blend the peaches and liquid until they’re pulverized into a puree. Allow the puree to cool entirely in your refrigerator before adding it to the bottom of champagne glasses – about 30 minutes.
Step 3
After adding the peach puree to champagne glasses, fill each glass with approximately 6 ounces of sparkling water. Plain sparkling water is perfectly fine for this recipe to let the natural peach flavor stand out. Otherwise, you may use peach-flavored sparkling water to enhance the flavor.
