Lacto-Fermented Jalapeño Rings
Salt brine and time transform raw jalapeño slices into funky, tangy, persistently hot rings — the heat rounded at the edges by lactic acid and the flesh gone from raw-vegetal to something deeper and fermented, like heat filtered through a wine cellar.

How to make it
Dissolve the salt completely in the water at a ratio of 2% salt by total weight (20g salt per 1000g water, or roughly 1 teaspoon per cup). Stir until no crystals remain. Taste it — it should be clearly salty but not overwhelmingly so, like well-seasoned soup. Do not use iodized salt (it inhibits fermentation) or chlorinated tap water (it kills the bacteria you need).
Pack sliced jalapeño rings tightly into a clean (not sterilized) wide-mouth mason jar. Tuck garlic cloves and peppercorns throughout. Pour the brine over the jalapeños to cover completely, leaving 2-3cm headspace. Weigh down the jalapeños with a small zip-lock bag filled with brine, a fermentation weight, or a folded cabbage leaf wedged under the jar neck — no jalapeño ring should break the brine surface. Cover loosely with a lid or cheesecloth.
Ferment at room temperature (18-22 C / 65-72 F) away from direct sunlight for 3-7 days. Burp the jar once daily if using a tight lid — just open briefly to release CO2. Check that jalapeños remain submerged each day. You will see: bubbles rising from the bottom (good), the brine gradually turning cloudy (very good), and the color shifting from bright green to olive-drab (normal and expected). Taste starting at day 3 — you want tangy, bright, and hot. Refrigerate when they reach your preferred sourness.
