Fermented Carrots
Fermented carrots are a crisp, tangy, and probiotic-rich snack — a simple way to bring gut-friendly bacteria into your daily diet. Naturally fermented in a light brine, they develop a pleasant sourness and subtle crunch that pairs beautifully with rice dishes, salads, or as a healthy snack on their own.
Ingredients
For a 1 L fermentation jar.
- 600 g carrot sticks (about 3-inch pieces)
- 20 g sea salt (1 tbsp)
- 300 ml filtered water (1½ cups)
Equipment
- 1 L glass fermentation jar
- Glass weight
- Grommet lid and airlock
Method
Prepare the carrots
Wash the carrots thoroughly and cut into even sticks about 2–3 inches long. You can peel them, but keeping the skin on helps encourage natural fermentation.
Sterilise the jar
Clean your 1 L fermentation jar with hot water and let it air dry completely to avoid contamination.
Make the brine
In a bowl, dissolve the sea salt in the filtered water. Add the carrot sticks to the jar, arranging them to minimise empty space. Place a glass weight on top, then pour the brine over until the carrots are fully submerged. Leave at least 2 inches of headspace for the gases to expand during fermentation.
Seal with an airlock
Close the jar with a grommet lid. Fill the airlock halfway with water so gases can escape while keeping contaminants out.
Ferment
Keep the jar in a warm, shaded spot (ideally 25–30°C) for 4–6 days.
Check daily
Check once a day to keep the carrots submerged, pressing gently if needed. Start tasting from Day 4 — they should be tangy and slightly sour with a crisp bite.
Store and enjoy
Once fermented to your liking, remove the glass weight and airlock, replace with a storage lid, and refrigerate. The carrots keep for up to 3 months.

Notes & variations
- Salt ratio: around a 3% brine (20 g salt per 600 g carrots + 300 ml water) preserves texture and flavour.
- Headspace: always keep at least 2 inches for safe bubbling.
- Airlock lid: lets gases out without letting air in, reducing the risk of mould.
- Fermentation time: warmer weather speeds it up; cooler slows it down.
- Storage: refrigerate once fermented; the flavour keeps deepening slowly.
With just carrots, salt, and patience you get a refreshing, probiotic-rich ferment that's versatile and nourishing. Try mixing in a few garlic cloves or dill sprigs for extra aroma.
