In a 1-quart jar, add your sliced fruit. Mash it with a spoon. Add in your honey and the insides of the probiotic capsules. Stir. Don't worry if the honey isn't dissolved.
Fill the rest of the jar up with filtered or distilled water, leaving 1 inch of headroom.
Put the lid on and leave your jar on the counter for 2-3 days.
Once or twice a day shake the jar briefly. If the lid starts to bulge and gets hard, open the jar briefly to let the air escape.
After 2 days, pour some of the liquid into a cup and taste it. If it's to your liking, strain out the fruit. It should be fruity and a little bit tangy. If it needs a little more time to ferment, keep it on the counter for an additional day or two. After you've strained out the fruit, keep in the refrigerator for 2-3 weeks.
After it's done fermenting, you can have a lot of fun with this by adding in some extras! The only limit is your imagination. I often add a bit more sweetener to taste (1-2 teaspoons) or sparkling water for extra fizz, herbs from my garden, etc. Have fun!! :)
Notes
Don't drink out of the jar! You'll introduce bad bacteria and we don't want that :)
