How to make it
- Wash and finely chop the tomatoes, capsicum, chiles and red onion, mince the garlic, and chop the cilantro; keeping the pieces small lets the brine penetrate evenly during fermentation.
- Combine all the vegetables in a clean non-reactive bowl, add the non-iodised salt and cumin, and mix thoroughly so the salt is evenly distributed; iodised salt and chlorinated surfaces can inhibit the good bacteria, so use clean filtered water and unbleached salt.
- Pack the mixture firmly into a sterilised glass jar, pressing down so the vegetables release their juices and sit below the surface of their own brine, leaving about 3 cm of headspace.
- Weigh the salsa down with a small clean glass weight or a brine-filled bag so everything stays submerged, then cover loosely with a lid or cloth that lets gas escape.
- Leave the jar to ferment at cool room temperature, around 18 to 22 C and out of direct sunlight, for 3 to 5 days, pressing the vegetables back under the brine once a day and releasing any built-up pressure.
- Taste daily from day three; when it has a pleasant tangy, lightly sour flavour and small bubbles appear, stir through the fresh lime juice.
- Seal the jar and transfer it to the refrigerator, where the fermentation slows right down; use within about two weeks and discard immediately if you ever see fuzzy mould or smell anything putrid.
