Slice peaches thinly.
Cut papaya into chunks.
Chop the almonds roughly.
Mix first 5 ingredients together, then pack into a 1L jar.
Mix up the brine, then pour into jar. Add additional water to cover ingredients, if necessary. Gently mix to distribute brine evenly.
Make sure food is still covered, then close jar and set to ferment for 12-24 hours. It will take longer the cooler the temperature is.
Taste, should still be pretty sweet but should also be quite bubbly when ready. Move to fridge for storage.
