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.
