If you are looking for a drink that is as kind to your gut as it is cooling for your body, look no further than fermented Ragi Ambli or Ambali. Often called the “poor man’s milk” in rural India, this traditional beverage is a nutritional powerhouse.
It is a common summer superfood in regions of Tamil Nadu, Karnataka, Andhra Pradesh, Maharashtra, and Orissa like Sattu Sherbet is for Bihar and eastern Uttar Pradesh.
- The Farmer’s Fuel: Historically, labourers would drink Ambli in the early morning before heading to the fields. The fermentation prevented dehydration under the scorching sun.
- Cultural Significance: In many folk traditions, Ragi is considered the grain of the “honest man.” The 16th-century poet Kanakadasa famously wrote Ramadhanya Charite, a poem where Ragi (the humble grain) wins a debate against Rice (the elite grain) by proving it is more resilient and beneficial to the common person.
- Calcium Rich: Great for bone health, and reduces internal body heat instantly.
Why Fermentation Matters?
While you can make “instant” ragi malt, the fermented version is where the magic happens. By letting the cooked ragi sit overnight:
- Probiotics flourish: Natural fermentation introduces healthy bacteria (lactobacillus) which improves gut health.
- Nutrient bioavailability increases: Fermentation makes it easier for your body to absorb calcium and iron.
- Low Glycemic Index: It provides sustained energy without the sugar spikes.
Ingredients You’ll Need
- Ragi (Finger Millet) Flour, sprouted one is even better for making ambli. Use the leftover flour to make this decadent Eggless Ragi Cake or the gluten free Ragi Roti.
- Buttermilk, the Indian Chaach, slightly sour works best. Avoid using yogurt or curd.
- Use rock salt or Himalayan pink salt.
- Seasoning: Onion, Ginger, Green Chilli, Fresh Coriander Leaves (add all or skip as per your taste preference.

How To Make Ragi Ambli
Step 1: The Slurry
- In a small bowl, mix ragi flour with ½ cup of water.
- Whisk thoroughly to ensure there are no lumps.
- This is crucial; adding dry powder to hot water will result in lumps difficult to handle rather than a smooth paste. Keep it aside.
Step 2: Cooking the Slurry
- Bring ½ Cup of water to a rolling boil in a heavy-bottomed pot.
- Turn the heat to low and slowly pour in the ragi slurry, stirring constantly with a whisk or wooden spoon.
- Cook for 5 to 10 minutes. The mixture will thicken and turn from a light brown to a dark, glossy melted, chocolate colour.
- The Test: Wet your finger and touch the surface. If the ragi doesn’t stick to your finger, it’s cooked.
Step 3: The Fermentation (The Secret Sauce)
- Once cooked, let the mixture cool completely in the pot.
- Method 1) Once at room temperature, cover it with a breathable cloth or a lid and let it sit overnight at room temperature (or for at least 8 to 10 hours).
- Method 2) Once at room temperature, make balls of ragi paste with wet fingers and drop them in a pot filled with clean drinking water. Cover and let it sit overnight at room temperature (or for at least 8 to 10 hours).
Pro Tip: If you live in an extremely hot humid climate, 5 – 6 hours might be enough. You want a faint sourdough-like aroma, slight bubbles on surface, not a harsh vinegar smell.
Step 4: The Final Mix
1) If you followed Method 1 of fermentation:
- In the morning, the ragi will have set into a thick jelly.
- Break up the “jelly” with a spoon.
- Add ½ cup of whisked buttermilk and salt.
- Add finely chopped onions, crushed ginger, and chopped coriander leaves for a refreshing crunch.
- Whisk until it reaches a drinkable consistency. If it’s too thick, add a splash of water.
2) If you followed Method 2 of fermentation:
- In the morning, whisk ragi balls with water.
- Add ½ cup of whisked buttermilk and salt. Whisk until it reaches a drinkable consistency.
- Add finely chopped onions, crushed ginger, and chopped coriander leaves for a refreshing crunch.
Hina’s Tried and True Tips
- Clay Pot: Ferment and store it in a clay pot to keep it naturally cool. Avoid using metal or plastic utensils/pots to avoid metallic reaction while fermenting the ragi. Glass, black stone, or earthen clay pots works best.
- The Tempering (Tadka): If you want to elevate the flavor, heat a teaspoon of oil, add mustard seeds and a pinch of asafoetida (hing), and pour it over the Ragi Ambli.
- Buttermilk Replacement: For a vegan ragi ambli, use thin, water coconut milk instead of buttermilk or add squeeze of lime juice in water for the hint of sourness.
