Fermented Ginger Carrots: Carrot Sticks in a Weighed Brine With Fresh Ginger

Fermented Ginger Carrots: Carrot Sticks in a Weighed Brine With Fresh Ginger

Transform fresh carrots and ginger into crunchy probiotic pickles in just 5 days. These lacto-fermented carrots boost gut health while delivering amazing tangy-spicy flavor and satisfying crunch.

At a glance

To make fermented ginger carrots, pack carrot sticks and thin slices of fresh ginger into a jar, cover them with a 2.5% brine (25 g non-iodized salt per litre of water), weigh them under the brine and leave at 18–24°C for 5–10 days, tasting from day 5. When they're pleasantly sour, refrigerate them and eat within a couple of months.

  • Brine: 2.5% salt by weight (25 g per litre of water), weighed.
  • Usually sour in 5–10 days at 18–24°C; refrigerate when ready.
  • Keep carrots 2 cm under the brine; discard if fuzzy mould appears.
  • A variation on basic fermented carrots, with sliced fresh ginger.
  • Fermented food, not a medicine: ginger's evidence is for nausea.

Fermented ginger carrots are carrot sticks packed with slices of fresh ginger and covered in salt brine until lactic acid bacteria turn them tangy, with a warm, peppery ginger edge. They’re a variation on our basic fermented carrots, which covers the method in more detail, and they’re good with rice bowls, sandwiches, cheese boards and noodle salads.

The Brine

Weigh the salt: 25 g of non-iodized salt per litre of water makes a 2.5% brine, in the 2–3% range used for brined vegetables. Spoon measures vary too much between salts – “2 tablespoons in 4 cups” can be anywhere from about 2% to nearly 4%. Use unchlorinated or boiled-and-cooled water, keep the carrots at least 2 cm under the brine with a weight, and ferment at room temperature, ideally around 18–24°C (NCHFP).

What to Expect

Bubbles and cloudy brine appear after a couple of days. Start tasting on day 5; most batches are pleasantly sour in 5–10 days, depending on the temperature. Then refrigerate them and eat them within a couple of months, while they’re still crisp. A flat white film is usually kahm yeast and can be removed; fuzzy or coloured mould, a rotten smell or slimy carrots mean the batch goes in the bin (NCHFP). See the troubleshooting guide for more.

About the Health Claims

Raw carrots are a good source of beta-carotene and fibre (USDA), and fermentation doesn’t make them a medicine. Eaten raw, fermented carrots contain live lactic acid bacteria, which makes them a fermented food rather than a probiotic (Marco et al., 2021). Ginger’s best evidence is for nausea: an overview of meta-analyses found it helped with nausea and vomiting after chemotherapy and surgery and showed promise in pregnancy, though the reviews’ methodological quality was low (Li et al., 2024). The few slices in a jar of pickles are there for flavour.

Recipe: Fermented Ginger Carrots

Makes
1 litre (1 quart) jar
Hands-on
20 min
Fermentation
5–10 days at room temperature
Salt
2.5% brine: 25 g salt per litre of water
Temperature
18–24°C (65–75°F)
Difficulty
Easy

Equipment

  • 1-litre wide-mouth jar
  • Scale
  • Fermentation weight
  • Loose lid or airlock

Ingredients

  • 600–700 g firm carrots (cut into sticks to fit the jar)
  • 30–40 g fresh ginger, thinly sliced (a 5 cm piece)
  • 2 cloves garlic, smashed (optional)
  • 1 tsp coriander seeds (optional)
  • About 600 ml water (unchlorinated, or boiled and cooled)
  • 25 g per litre of water non-iodized salt (about 15 g for 600 ml)

Method

  1. Dissolve the salt in the water (25 g per litre).
  2. Put the ginger, garlic and coriander in the jar and pack the carrot sticks in upright, leaving 3–5 cm of headspace.
  3. Pour in brine to cover the carrots by 2 cm and add a weight.
  4. Cover loosely or fit an airlock and leave at 18–24°C, out of direct sun.
  5. Check daily, keeping everything submerged; taste from day 5.
  6. When pleasantly sour (usually 5–10 days), close the jar and refrigerate. Eat within a couple of months.
  7. Discard the batch if fuzzy mould appears, it smells rotten or the carrots turn slimy.

Frequently asked questions

How long do fermented ginger carrots take?

Usually 5–10 days at 18–24°C. Taste from day 5 and refrigerate when they're as sour as you like.

How much salt do I need?

25 g of non-iodized salt per litre of water, a 2.5% brine. Weigh it rather than using spoons.

Do I need to peel the ginger?

No; scrub it and slice it thin. Peeled ginger works just as well.

How long do they keep?

A couple of months in the fridge, under the brine; they slowly soften and get more sour.

Are fermented ginger carrots probiotic?

They contain live lactic acid bacteria when eaten raw, which makes them a fermented food; 'probiotic' is reserved for specific strains with proven benefits.

Why is my brine cloudy?

Cloudy brine is normal: it's bacteria and yeast from active fermentation.
