Saunf Ajwain Water: The After-Dinner Jug, Made Properly
Fennel and carom seed, steeped in hot water and left to cool in a jug, is the quietest drink in the subcontinental kitchen and possibly the most used. It costs pennies, takes five minutes of actual work, and sits on the counter after dinner.
At a glance
- Makes: about 1 litre (5 servings of 200 ml)
- Takes: 10 minutes of work, then it sits
- Traditionally drunk: after a heavy meal, warm or at room temperature, in small glasses
- Go easy if: you are pregnant, you have reflux or a stomach ulcer, you have liver problems, or you are giving it to a small child

The jug on the counter
Saunf, fennel seed, is what gets passed round at the end of a meal in an Indian restaurant, usually sugar coated and in a little steel bowl. Ajwain, carom seed, is the sharp thyme-smelling seed that goes into parathas and pakora batter and that every grandmother in Punjab and Sindh keeps within arm’s reach of the stove.
Put them together in hot water and you get the household after-dinner drink. Nobody serves this to guests with any ceremony. It lives in a steel jug or an old glass bottle, gets made after a big cooking day, and gets poured out in small glasses once the plates are cleared. In many homes a warm cup goes to whoever is complaining loudest about having eaten too much.
Traditionally it is drunk after a heavy meal, and that is the entire framing. People have long done this. It is a pleasant, faintly sweet, aniseedy warm water that ends a meal, and it is not a remedy for anything.
The two seeds
They are opposites and that is why they work together. Fennel is sweet, soft, cooling, almost liquorice-ish. Ajwain is hot, medicinal, bitter and sharp, with a thyme-like smell that catches the back of the nose. Fennel makes the drink pleasant. Ajwain makes it interesting. Get the ratio wrong towards ajwain and it becomes hard to drink, which is why the proportions below are heavily weighted to fennel.
Buy both whole. Ground ajwain goes stale within weeks and tastes of dust. Good fennel seed is green-grey and smells sweet when you rub it between your palms. Good ajwain is tiny, ridged, grey-brown, and one seed crushed between the fingers should perfume your whole hand.
| Ingredient | Amount | Why it’s there |
|---|---|---|
| Water | 1 litre | The jug |
| Fennel seeds (saunf) | 2 tsp (about 6 g) | Sweet, cooling, the main flavour |
| Carom seeds (ajwain) | 1/2 tsp (about 1.5 g) | The sharp, thyme-like counterpoint. Do not increase this. |
| Cumin seeds (jeera) | 1/2 tsp (optional) | Adds an earthy note, common in Gujarati versions |
| Coriander seeds | 1/2 tsp (optional) | Softens and rounds the whole jug |
| Fresh mint | 6 leaves (optional) | Added off the heat, for a summer jug |
| Rock salt or black salt | 1 small pinch (optional) | Makes it taste like a drink rather than water |
| Lemon | 2 thin slices (optional) | Added cold, for the room temperature version |
| Jaggery or honey | Usually none | This is not meant to be sweet. Leave it out. |
The method
The only technique worth naming is the toast, and it is optional but it changes everything. Thirty seconds in a dry pan wakes the seeds up. Sixty seconds burns them and makes the whole litre taste acrid, and there is no recovering from that.
- Optional but recommended: put the 2 tsp of fennel and 1/2 tsp of ajwain in a dry pan over medium heat. Shake the pan constantly. After 30 to 40 seconds they will smell nutty and the fennel will be a shade darker. Tip them straight out of the pan onto a plate. Do not leave them in the hot pan, they keep cooking and they burn.
- Crush the seeds lightly, just a few presses in a mortar. You want them cracked, not powdered. Powder makes the water cloudy and slightly bitter.
- Bring 1 litre of water to a boil in a pan or kettle.
- Take it off the heat and let it stand for 1 minute, so it drops to roughly 90°C. Add the crushed seeds, plus the cumin and coriander if you are using them.
- Cover and leave it to steep for 15 minutes. Longer than 30 minutes and the ajwain starts to take over and it goes harsh. Fifteen is the sweet spot.
- If you want mint, add it after 15 minutes, once the water has cooled to hand-warm, and leave it 5 minutes more.
- Strain into a jug through a fine sieve. Add the pinch of rock salt and stir. Taste it. It should be faintly sweet, slightly savoury, with a warm aniseed finish.
- Serve warm in small glasses straight away, or let it come down to room temperature and add the lemon slices. Both are correct.
Thirty seconds in a dry pan is the whole trick. Sixty seconds and you have ruined a litre.
Variations people actually make
The overnight cold version is common in summer: skip the boiling entirely, put the crushed seeds in a litre of room temperature water, cover, and leave it in the fridge overnight. It is gentler, cleaner and less aromatic, and it is what a lot of Gujarati and Rajasthani households do when it is forty degrees outside.
Adding cumin makes it earthier and is standard in some regions. Coriander seed softens it. A bruised 3 cm piece of ginger turns it into something closer to a winter drink. A single crushed cardamom pod makes it prettier. Fresh mint and lemon make it something you would happily serve at a summer lunch.
The sugar-coated mukhwas fennel from restaurants is not what you want here. Plain seed only.
The old habit is to make this in the same pan the food was cooked in, once it is wiped, while the stove is still warm, so that nothing extra gets used. The jug then sits out, uncovered except by a plate, and gets finished by morning. If you are going to leave it out rather than refrigerate it, finish it within the evening. A jug of spiced water standing on a warm counter all night is not something to drink the next day.
Common mistakes
Too much ajwain. It is the most common error and it makes the jug undrinkable, bitter and medicinal. Half a teaspoon in a litre. Really.
Burning the seeds. Thirty seconds, constant movement, out of the pan immediately.
Grinding to a powder. Cloudy, muddy water that has to be strained twice.
Over-steeping. Leaving the seeds in the jug all evening keeps extracting the harsh end of the ajwain. Strain at 15 to 20 minutes.
Boiling water poured straight on. A brief pause off the boil gives a cleaner, sweeter extraction.
Sweetening it. It is a savoury-leaning water. Sugar makes it taste like weak liquorice cordial.
How much, how often
A serving is a small glass of about 200 ml, drunk after dinner. A litre made in the evening comfortably does a family of four or five with a glass left over.
The traditional pattern is a glass after a heavy meal, a few evenings a week, and more often during festival weeks when the cooking is richer. Plenty of households have it nightly. It is caffeine free, unsweetened and essentially flavoured water, so it sits at the very gentle end of this series. Even so, the sensible ceiling is two or three glasses a day rather than replacing all your water with it, mostly because ajwain is a strong seed and there is no benefit to loading up.
Frame it the way families do: the jug that comes out after dinner. Not a routine, not a course, not a dose.
You are pregnant. Both fennel and ajwain in amounts beyond ordinary cooking are things people are commonly advised to be cautious with in pregnancy, so do not drink this as a daily jug while pregnant without asking your own midwife or doctor. The same caution applies while breastfeeding. If you have a stomach ulcer, gastritis or reflux, ajwain can be irritating and you may find it burns, in which case leave it out and make a plain fennel water instead. If you have liver disease, be cautious with ajwain in any regular quantity and ask your doctor. Very small children should not be given this as a drink, and the old practice of giving seed waters to babies is not something to copy: infant feeding is a conversation for your health visitor or doctor, not a recipe column. Fennel can occasionally cause a reaction in people who are sensitive to other plants in the carrot and celery family. If you take blood thinners, blood pressure medication or diabetes medication, or you have any ongoing health condition, ask your own doctor before making this a daily habit. Overdoing it usually shows up as a burning stomach, nausea or heartburn, and the answer is to stop. This is food and tradition writing by a cook, not medical advice, and nothing here treats or prevents any condition.
Storing and reheating
This is the one drink here that genuinely suits being made ahead. Strain it, let it cool, and keep it covered in the fridge for up to 48 hours. It holds its flavour well because there is no dairy, no tea leaf and no sugar in it. Always strain before storing, because seeds left in the jug keep extracting and by the next day the balance will have tipped hard towards the ajwain.
Reheat a glass at a time in a pan to just warm, or in the microwave if you must. It does not need to be hot. In many homes it is drunk at room temperature year round, and the fridge version with a slice of lemon is the summer default.
If it smells at all off, or if it has been standing out at room temperature for more than about six hours, pour it away and make a fresh litre. It costs almost nothing.
Try this this week
Make a litre on a night when you have cooked something rich, and put it on the table in a glass jug with a few lemon slices instead of a jug of plain water. See whether it gets finished. In most houses it does, and then it becomes a habit without anyone deciding to start one.
If you like this one
For the after-dinner slot with tea in it instead, sulaimani chai does the same job with black tea and lemon. Haldi doodh is the later, bedtime drink, and adrak tulsi chai is the morning one. If you have been reading about mulethi tea and wondering what an everyday alternative looks like, this jug is the answer. The whole series is under Desi Remedies.
Can I make it without ajwain?
Yes, and plain fennel water is lovely, milder and sweeter. It is the right call if you find ajwain harsh or if you have a sensitive stomach. Use 3 tsp of fennel in a litre if ajwain is out.
Warm or cold, which is traditional?
Both. Warm after a heavy winter meal, room temperature or cold in summer. The one thing you rarely see is ice, which numbs the flavour. Cold from the fridge, yes. Over a tumbler of ice, less so.
Why is my water bitter?
Too much ajwain, burnt seeds, or steeping too long. Check the ratio first, since that is the usual cause. Half a teaspoon of ajwain to two teaspoons of fennel per litre is the balance to keep.
Can I reuse the strained seeds for a second jug?
Not really. The second extraction is thin and slightly stale tasting. The seeds cost very little, so use fresh ones. The spent seeds go on the compost.
