When to Add Salt to Daal, Rajma and Meat (Namak Kab Dalein)
“Don’t put namak in the daal until it’s cooked, or it’ll stay hard.” Your nani probably said it, and it’s mostly wrong. Salt added early doesn’t toughen daal or rajma; if anything, salt in the soaking water makes skins softer. The real hardeners are old stock, hard water and sour ingredients added too soon.
Quick facts
- Soaking daal and rajma: salt the soak, about 1 level tsp per litre, then rinse
- Cooking daal: salt at the start or the end; both work, early salt seasons more evenly
- What actually slows softening: tomato, imli, amchur, lemon, sugar and gur added before the pulse is soft
- Meat: salt 40 minutes to a day ahead, or right before cooking
- Rice: salt the cooking water, not the finished rice

Where the “salt makes daal hard” belief came from
Sounds sensible. Salt pulls water out of things (think of salted cucumber weeping in a bowl), so surely it stops beans taking water in? That was the logic, and generations of cooks passed it on, along with a lot of undercooked rajma.
Here’s what really happens. The skin of a bean or chana is held together by pectin (a plant gum) that’s stiffened by calcium and magnesium. When beans sit in salted water, sodium from the salt swaps places with some of that calcium. The skin loosens. Water then gets in more evenly from every side, the beans soften more reliably at the same pace, and far fewer of them burst open and turn to mush in the pot while their neighbours are still chalky in the middle.
So the old rule had it backwards for soaking. For the cooking stage, salt makes very little difference to texture at normal kitchen amounts. It can slow things a touch in a pot without a lid, which is probably where the belief took root, but a pressure cooker flattens that difference within a whistle or two.
If your daal stays hard, look at the packet date and the tomatoes before you blame the salt.
When to add salt to daal and rajma
- Soak with salt. For 1 cup of rajma, kabuli chana or lobia, use 4 cups of water and 1 level teaspoon of salt. Soak 8 to 12 hours. Drain and rinse well.
- Salt the cooking water lightly. Around half a teaspoon of salt per cup of dry daal is a sensible start. Early salt goes right into the grain, so the daal tastes seasoned all through rather than salty on top and bland underneath.
- Pressure-cook as usual. Rajma: 1 cup soaked with 3 cups fresh water, 6 to 7 whistles, then 10 to 15 minutes on low. Arhar or masoor: 3 to 4 whistles. Our whistles and water chart covers every daal.
- Taste and adjust at the end. Cooking concentrates daal, so final salt goes in after the cooker opens and it’s back on the flame.
- Add the sour things last. Tomato, imli, amchur and lemon go in the tadka or after the daal is soft. Acid firms up pectin, and so does sugar or gur, which is why a sweet-and-sour Gujarati daal is sweetened once the daal is done.
One rule doesn’t change with timing. Raw rajma and other kidney beans contain a natural toxin (phytohaemagglutinin) that only a hard boil destroys, so soaked beans must be boiled at full heat for at least 10 minutes, or pressure-cooked properly. Slow cookers on low don’t get hot enough. The full safety story is in our rajma and lobia safety guide.
When to salt meat: early or at the last minute
Meat works differently. Salt on raw meat first draws juices out to the surface. Leave it long enough and that salty liquid is pulled back in, where it loosens muscle proteins so the meat holds more water as it cooks. Juicier. More evenly seasoned.
The awkward window is in between. Salt a piece of chicken or a steak and cook it 10 minutes later, and the surface is wet with drawn-out juice, so it steams instead of browning. That’s the moment to avoid.
The simple meat rule
For tikka, chops, seekh or roast chicken, salt at least 40 minutes ahead, or overnight in the fridge on a plate. If you forgot, salt right before it hits the pan. For a salan or karahi where the meat is bhuno’d in masala, add salt during bhunao; the long cooking evens it out anyway.
Marinades with dahi and lemon also carry salt into the meat, and there’s no need to salt again separately. Keep salted raw meat covered on the lowest fridge shelf, never on the counter, and cook it within a day or two.
Salt in rice water, pasta and boiled vegetables
Rice and pasta only absorb salt while they’re cooking, so salt sprinkled on afterwards just sits on the surface and you end up needing more of it to taste the same thing.
For boiled-and-drained rice, about 1 teaspoon of salt per litre of water is plenty. For absorption-method rice (the water all gets soaked up), think half a teaspoon per cup of rice. More detail on ratios is in our basmati water ratio guide. Boiled potatoes and vegetables work the same way: salted water, better flavour, less salt at the table.
Does salt make water boil faster or hotter? Not in any way a cook would notice. The amounts in a pot raise the boiling point by a fraction of a degree. It’s there for taste.
Myth: salt at the end means less salt overall
Often it’s the opposite. Food salted early tastes seasoned through, so people reach for the salt shaker less. Food salted only on top tastes flat underneath, and the usual response is to add more.
What really cuts sodium is the total amount, not the timing. The WHO’s limit for adults is under 5 grams of salt a day, about one level teaspoon, and that includes the salt already in bread, achaar, namkeen, papad and packet masalas. One gram of salt carries about 400 mg of sodium.
If you have high blood pressure, heart failure or kidney disease, the timing trick matters far less than the total, and your doctor may set a lower limit than the general one. Our guide on salt and blood pressure in desi food shows where the hidden salt sits in a typical day.
Salt substitutes sold as “low sodium” often replace sodium with potassium, which can be dangerous for people with kidney disease or those taking certain blood pressure medicines (such as spironolactone, ACE inhibitors or ARBs). Speak to your doctor before switching. Babies under 1 need no added salt in their food at all. And never taste raw or half-cooked rajma to check the seasoning.

Salt and cooking: what people ask
When to add salt in daal, before or after cooking?
Either works. Adding some before gives more even seasoning; adjust the final amount after cooking, because daal thickens and concentrates as it simmers.
Does salt make beans hard?
No. Salt in the soaking water actually softens bean skins. Old beans, hard water and acidic ingredients added early are what keep beans hard.
Should salt be added while soaking rajma?
Yes, about 1 level teaspoon per litre. It softens the skins and fewer beans split. Drain and rinse, then cook in fresh water.
Why is rajma still hard after pressure cooking?
Usually the beans are old, the water is hard, or tomato went in with the beans. Soak longer in salted water, use fresh stock, and add tomato masala after the rajma is soft.
When to add salt to chicken curry?
During bhunao, with the masala. The long cooking spreads it through the meat. For grilled or fried chicken, salt 40 minutes ahead or right before cooking.
Does salt in water make rice cook faster?
No. The effect on boiling point is tiny, a fraction of a degree, so salt is only there for flavour, and it works best in the water rather than sprinkled on after.
How much salt per day is safe for adults?
Under 5 grams, about one level teaspoon, counting the salt already in bought foods. Your doctor may set a lower figure if you have high BP or kidney disease.
Can salt be added to baby’s daal?
Not under 1 year. A baby’s kidneys can’t handle added salt, and plain daal with a little ghee or jeera is enough flavour for them.
Is it better to add salt at the end to reduce sodium?
Not really. Food salted only at the end often tastes flat, so people add more. Cutting the total amount and reading labels matters far more than timing.
Why does meat release water after salting?
Salt draws juice to the surface first. Given 40 minutes or more, most of that liquid is pulled back in, and the meat ends up juicier and better seasoned.
