Hard water making your dal tough? Find out why and fix it.

Hard water & cooking

If your dal never softens and tea looks dull, stay till the end for the simple water trick that solves it.

What hard water is

Rain is soft, but as it passes through limestone it picks up calcium and magnesium. The result is hard water that leaves white spots on glass and makes soap foam poorly.

Why dal stays hard

Lentils and beans are held together by pectin. Calcium and magnesium lock onto that pectin, forming extra cross-links that keep the walls stiff, so the dal stays tough.

Quote

Old dal plus hard water is the pair that breaks pressure cookers' hearts.

Cook dal in soft water

The classic shortcut is a pinch of baking soda, but it can sap B vitamins and leave a soapy taste. Better is to soak the dal in soft water, RO, filtered, or boiled and settled, add a teaspoon of salt per litre, and use fresh, plump dal.

Soak time

Whole chana or rajma need eight to twelve hours of soaking in soft water to break down the pectin.

Test your water

Brew two identical cups of black tea, one with tap water, one with RO or bottled water. Let them steep three minutes, then compare the surface film and taste.

Remove scale

White crust in kettles and pressure cookers is calcium carbonate. Fill the pot with equal parts white vinegar and water, bring to a boil, turn off and let sit thirty to sixty minutes, then scrub and rinse.

Scale removal time

A half-hour to an hour of soaking clears most deposits and keeps the vent pipe clear.

The one fix to try

The single most effective habit is to always soak and cook your dal in soft water, RO, filtered, or boiled and settled, plus a pinch of salt in the soak. It softens the beans, clears the tea, and prevents scale.
