Lacto-Fermentation — Wild Vegetable Ferments

Ingredients

• For brine
• 500 ml unchlorinated water, room temperature
• 30 g fine sea salt (6% by weight of total vegetables)
• 10 g raw cane sugar
• 3 bay leaves
• 5 juniper berries, crushed
• 2 tsp Tellicherry black pepper, cracked
• For fermentation vegetables (choose one or combine):
• 300 g green Castelvetrano olives, pitted
• OR
• 300 g Brussels sprouts, quartered
• OR
• 300 g watermelon radish, cut into 1 cm batons
• OR
• 300 g daikon radish, cut into 2 cm spears
• OR
• 300 g young carrots, cut into 3 cm batons

Method

1. 1
   Dissolve fine sea salt and raw cane sugar in 500 ml unchlorinated water at room temperature (18–22°C) by stirring for 90 seconds; verify no crystals remain; salt concentration should reach 6% by weight for proper lacto-fermentation environment.
2. 2
   Prepare vegetables: remove blemishes, trim ends, cut into uniform 2–3 cm pieces; pack tightly into a clean, sterilized 500 ml glass jar, leaving 3 cm headspace.
3. 3
   Add bay leaves, crushed juniper, and black pepper evenly throughout packed vegetables; pour brine until vegetables are completely submerged (critical—exposure to air causes mold).
4. 4
   Place a weight (glass fermentation weight, cabbage leaf, or small glass dish) atop vegetables to maintain full submersion; cover jar with cheesecloth or coffee filter secured with rubber band (allows CO₂ to escape while blocking airborne contaminants)—do NOT seal airtight lid yet.
5. 5
   Place jar at room temperature (18–22°C) away from direct sunlight; observe daily for 5 days—white foam (wild Leuconostoc bacteria) will form on surface; skim away daily with clean spoon; cloudiness and bubbles are normal signs of active fermentation.
6. 6
   After 5 days of active fermentation, taste daily for desired sourness and crunch (fermenting vegetables retain firmness 7–10 days but soften after 14 days); fermentation completes when bubbling stops and taste reaches desired acidity (typically 12–18 days total).
7. 7
   Once fermented to preference, remove weight, cover jar with airtight lid, and transfer to 4°C; lacto-fermented vegetables remain shelf-stable and improve in flavor for 6 months; serve as condiment, side, or pickled vegetable component.
