Kaali Gajar Di Kanji
Fermented black carrot drink, tangy and excellent for digestion.
About this dish
Kaali Gajar Di Kanji is a traditional fermented probiotic drink prepared during the transition from winter to spring. It is uniquely made with black carrots (Kaali Gajar), which give the drink its iconic deep purple-burgundy hue. Beyond its striking appearance, it is a powerhouse of gut-friendly bacteria and is famously served during the festival of Holi to aid digestion after heavy festive treats.
Ingredients
The Base
- 500g Black Carrots (or deep purple carrots)
- 2 liters Filtered water (boiled and cooled)
- 1 medium Beetroot (optional, for deeper color if using orange carrots)
The Fermentation Mix
- 4 tbsp Yellow Mustard seeds (Rai), coarsely ground
- 2 tbsp Black Salt (Kala Namak)
- 1 tbsp Sea Salt
- 1 tsp Red Chilli powder
- 1/2 tsp Roasted Cumin powder
Method
- 1
Prepare the vegetables
Wash the black carrots and beetroot thoroughly to remove any soil. Peel them and cut into 2-inch long batons (like thick matchsticks). Avoid slicing them too thin, as they need to stay firm during the fermentation process.

Sterilize the jar
Wash a large glass or ceramic jar (Martabaan) with hot water and dry it completely in the sun. Avoid using plastic or metal containers, as the acid from fermentation can react with them.

Combine ingredients
Place the carrot and beetroot batons into the jar. Add the ground mustard seeds, black salt, sea salt, red chilli powder, and roasted cumin powder. The mustard is the key fermenting agent that provides the signature tang.

Add water
Pour the 2 liters of cooled, filtered water into the jar. Stir the mixture with a clean wooden or plastic spoon to ensure the spices are well distributed.

Seal the jar
Cover the mouth of the jar with a clean muslin or cheesecloth. Secure it with a rubber band or string. This allows the gases produced during fermentation to escape while keeping dust and insects out.

Sun-fermentation
Place the jar in a sunny spot (balcony or windowsill) for 3 to 4 days. The sun's warmth facilitates the growth of natural probiotics. If it is very cold, it may take up to 6 days.

Daily maintenance
Once a day, open the cloth and stir the Kanji with a dry spoon. You will notice the color deepening to a rich violet and a pungent, sour aroma developing as the mustard seeds do their work.

Taste test
After the 3rd day, taste a small spoonful. If it is sharp, tangy, and slightly fizzy, it is ready. If it still tastes like salty water, let it ferment for another day.

Strain and store
Once fermented, you can strain the liquid into bottles or keep the carrots in (they become delicious 'pickled' snacks). Store the Kanji in the refrigerator to stop the fermentation process and serve chilled.
Notes & variations
- If black carrots are unavailable, use regular orange carrots and double the beetroot quantity to achieve the purple color.
- The black salt is non-negotiable for the authentic sulfurous 'chaat' flavor.
- Always use a dry spoon to serve; any moisture or saliva will cause mold to grow.
- Kanji stays fresh in the refrigerator for up to 2 weeks.
Serve with
Serve in small glasses as a digestive appetizer before a heavy meal, or with Urad Dal Vadas (Kanji Vada).
Cook's note
Do not skip grinding the mustard seeds; the coarse powder exposes the oils necessary for a successful, pungent fermentation.
