Lacto-Fermented Kohlrabi Pickle with Fennel Seed, Dill & Chili

This is a clean, crunchy lacto-ferment that turns kohlrabi into bright, lightly tangy pickles with a subtle anise lift from fennel seed and a fresh, green finish from dill. It’s simple enough for everyday snacking, but the spice profile tastes polished—like a composed garnish for grilled meats, rice bowls, or sandwiches. Expect a crisp bite, gentle funk, and a glossy, briny snap that gets more complex over 5–10 days.

Total time: 10095 minutes

Yield: Makes about 1 L jar (about 8 condiment servings)

Ingredients

  • Kohlrabi, peeled, cut into batons (about 650 g; ~2 medium bulbs)
  • Non-iodized fine sea salt (20 g; about 1 Tbsp + 1 tsp)
  • Filtered water (980 g; about 980 mL / 4 cups + 2 Tbsp)
  • Garlic, lightly crushed (2 cloves; ~6 g)
  • Fresh dill (10 g; about 1 loose cup fronds, or 2 dill sprigs)
  • Fennel seeds (2 g; about 1 tsp), lightly crushed
  • Coriander seeds (2 g; about 1 tsp), lightly crushed
  • Dried chili flakes (1 g; about 1/2 tsp) or 1 small dried chili
  • Black peppercorns (1 g; about 1/2 tsp)
  • Bay leaf (1; optional)

Instructions

  1. Wash a 1 L jar and lid with hot soapy water, rinse well, and let air-dry. (Clean is key; sterile isn’t required, but avoid residue.)
  2. Peel the kohlrabi generously (remove fibrous outer layer), then cut into 8–10 cm batons (think “fry” shape). Keep thickness fairly even so they ferment at the same pace.
  3. In a bowl or measuring jug, dissolve the salt in the water until the brine tastes pleasantly salty but not harsh.
  4. Add garlic, dill, fennel seed, coriander seed, chili, peppercorns, and bay leaf (if using) to the bottom of the jar.
  5. Pack kohlrabi batons in tightly so they don’t float, leaving 2–3 cm of headspace.
  6. Pour in brine to fully cover the kohlrabi by at least 2 cm. Use a clean fermentation weight or a small food-safe zip bag filled with a little extra brine to keep everything submerged.
  7. Loosely cap the jar (or use an airlock lid). Set it on a plate (to catch any overflow) at cool room temperature—ideally 18–22°C.
  8. For days 1–3, check daily that the vegetables stay submerged. You should see tiny bubbles and the brine may turn slightly cloudy—good signs.
  9. Start tasting on day 4. It’s ready when it smells pleasantly sour (like fresh pickles, not rotten), tastes tangy, and the batons are still snappy.
  10. Once you like the acidity (typically 5–10 days), tighten the lid and refrigerate. The flavor will keep developing slowly.
  11. To serve it in a more elevated way: drain a portion and toss with a drizzle of good olive oil and a pinch of flaky salt, then top with more fresh dill fronds and a few crushed fennel seeds. Serve alongside grilled chicken, burgers, or rice bowls for a crisp, aromatic counterpoint.

Notes

Salt choice: use non-iodized salt (iodine can slow fermentation). Water: filtered is best if your tap water is heavily chlorinated. Flavor tweaks (still simple): swap dill for tarragon; add 1–2 thin slices of fresh ginger; or add a small strip of kombu for subtle umami. Storage: refrigerated, it stays crisp 3–4 weeks (often longer). Keep pieces submerged in brine for best texture. Food safety: fermentation speed depends on temperature; warmer goes faster and softer, cooler goes slower and crunchier.
