Ajwain (Carom Seeds): A Chef’s Guide to Uses, Benefits, Nutrition & Side Effects
In my 13 years running hotel kitchens, from bustling banquets to high-stakes a la carte service, there is one spice jar that gets reached for just as often as the salt: Ajwain.
While most people know it as a simple digestive aid, for a chef, it is a precision tool. It cuts through the richness of deep-fried batters, balances the earthiness of heavy lentils, and adds a sharp "top note" of thyme-like freshness that lifts a dish instantly.

What Is Ajwain? (Origin & Taste Profile)
Ajwain comes from a small herbaceous plant of the Apiaceae family (the same family as cumin, fennel, and parsley). The seeds are tiny, ridged, and brownish-grey, often mistaken for celery seeds due to their appearance.
Ajwain, known as Carom Seeds in English, is a pungent Indian spice traditionally used for digestion, flavor balance, and cooking heavy foods.
The Chef’s Taste Profile
If you taste a raw seed, you’ll get a flavor that is:
Sharp and Hot: It has a pungent kick similar to oregano but much stronger.
Slightly Bitter: This bitterness is crucial for cutting through fats (ghee/oil).
Medicinal: That distinct aroma comes from Thymol, the essential oil responsible for its digestive power.
Because it is so potent, we use it sparingly—a single pinch can flavor an entire pot of curry.
One Spice, Many Names: A Regional Guide
In a professional kitchen, we often have staff from all over India. To avoid confusion during prep, knowing the regional names is essential. Here is your quick translation guide:
| Language | Name | Culinary Use |
|---|---|---|
| English | Carom Seeds / Bishop’s Weed | Savory baking & breads |
| Hindi/Punjabi | Ajwain (अजवाइन) | Samosa dough & Tadka |
| Marathi | Ova (ओवा) | Besan Pithla & Bhajis |
| Tamil | Omam (ஓமம்) | Omam Water & Murukku |
| Telugu | Vamu (వాము) | Rice & Savory Snacks |
| Gujarati | Ajmo (અજમો) | Thepla & Farsan |
Chef’s Technique: The "Palm Rub"
The Technique:
Take a teaspoon of seeds in your left palm.
Use the heel of your right hand to rub them firmly in a circular motion for 5–10 seconds.
The Result: You will smell the aroma intensify immediately. This "bruising" ensures the flavor distributes evenly throughout your Onion Samosa crust or Paratha dough.

Functional Health Benefits
In the hospitality industry, we don't just cook for taste; we cook for digestion. Here is why ajwain is a non-negotiable ingredient in heavy meals:
1. The "Heavy" Food Cutter (Digestion)
Ajwain is best known for helping with gas, bloating, and heaviness. That is why you will always find it in the batter of deep-fried dishes like Prawns Koliwada. The thymol stimulates the stomach to release gastric juices, helping break down rich oils and batters faster.
2. Instant Acidity Relief
A common "Grandmother's Trick" that works: chewing a pinch of raw ajwain with black salt and warm water. It acts as a natural antacid.
3. Metabolic Boost
For those on a weight loss journey, drinking Ajwain water may support digestion and appetite control, which indirectly helps people stay consistent with their dietary goals. (Check your daily needs with my Daily Calorie Intake Calculator).
How Chefs Use Ajwain in Indian Cooking
From a professional perspective, here is how we layer this spice into our menus:
The Dough Secret: We add it to Poori and Samosa dough not just for flavor, but to prevent the "bloated" feeling guests get after eating refined flour (Maida).
The Tadka Timer: Ajwain burns faster than cumin or mustard seeds. In a hot pan, it needs only 3–5 seconds to sizzle. Any longer, and it turns bitter and ruins the dish.
The Perfect Pairing: I often mix ajwain with Coriander Seeds for a complex tempering. The citrusy notes of coriander balance the sharp heat of ajwain perfectly.
Best Way to Consume Ajwain Daily
Jeera Ajwain Saunf water benefits (The "Trinity" Detox Water)
Jeera Ajwain Saunf Ka Pani
"A powerful digestive tonic combining the 'Holy Trinity' of Indian spices: Ajwain, Jeera (Cumin), and Saunf (Fennel). This warm infusion aids digestion, relieves bloating, and acts as a gentle metabolic booster—perfect for post-meal recovery."
Ingredients
- 1/4 tsp Ajwain (Carrom Seeds) for gas relief
- 1/4 tsp Jeera (Cumin Seeds) for Iron & digestion
- 1/4 tsp Saunf ( Fennel) for cooling
Instructions
- In a saucepan, add 2 cups of water along with the Ajwain, Cumin (Jeera), and Fennel (Saunf) seeds. Bring the mixture to a rolling boil over medium heat.
- Immediately reduce the flame to low and let it simmer gently for 5–7 minutes. The water should reduce by half (to approx. 1 cup) and turn a clear, golden amber color.
- Turn off the heat and strain the tea into a mug using a fine-mesh sieve. Let it cool slightly and drink it lukewarm for the best digestive results.
Chef's Notes
- Never use powdered spices for this. Powders will make the water muddy and gritty. Using whole seeds ensures a clear, golden bouillon-like consistency.
- Never boil this mix on high heat. Once the water bubbles, turn the flame to the lowest setting. A rapid boil destroys the delicate essential oils in the fennel (Saunf), leaving you with a flat, bitter taste.

Side Effects & Who Should Avoid It
Ajwain has a "Garam Taseer" (Hot Potency). While beneficial, more is not always better.
Avoid Excess: Consuming more than 1 teaspoon a day can lead to heartburn or nausea.
Pregnancy Caution: While small amounts in food are safe, concentrated ajwain water should be avoided in pregnancy due to its potential to induce heat in the body.
Stomach Ulcers: If you have severe acidity or ulcers, the sharp oils might irritate the stomach lining.
Frequently Asked Questions
Q: What is ajwain called in English?
Ajwain is known as Carom Seeds or Bishop’s Weed in English.
Q: Is ajwain the same as thyme?
No. They smell similar because they both contain thymol, but they are completely different plants. Thyme is a herb; ajwain is a seed.
Q: Can we eat ajwain daily?
Yes, in small amounts (¼ to ½ tsp) to support digestion.
Q: Ajwain seeds vs. Ajwain leaves?
The plant commonly called “Ajwain” in Indian homes is actually Mexican Mint (Indian Borage) . Its leaves smell like ajwain due to similar aromatic compounds, but the seeds come from a completely different plant.
Chef’s Final Note
Ajwain might be small, but it does the heavy lifting in Indian cuisine. Whether you are tempering a Dal or kneading a Paratha, remember the Palm Rub rule, and you’ll unlock a flavor that takes your home cooking to professional standards.
