Want to save fuel while cooking? Here is how you can use a pressure cooker effectively

I love the pressure cooker as it is one of the most underrated tools in the kitchen — affordable, dependable, and surprisingly intuitive. It “knows” when food is cooked, ensuring consistent results no matter who is doing the cooking. It handles everything from the most delicate vegetables to the toughest meats with equal ease. Fast, largely maintenance-free, and built to last a lifetime, it is a device that truly pays for itself.

There is just one catch: you need to learn how to use it well.

A pressure cooker can save you over 50% on fuel — but only if you use it right. Here’s how:

Always pre-soak

Pre-soaking rice, dal, and rajma significantly reduces cooking time. Remember, cooking only begins once water reaches the core of the ingredient; skipping this step means you’re simply burning extra fuel. By the same logic, always thaw frozen ingredients before cooking, and avoid large chunks. A whole potato, for instance, takes far more fuel to cook than one that’s been chopped.

Use as little water as possible

Water absorbs heat. The more you add, the more fuel you waste. Vegetables, meats, and seafood already have high water content and need very little added water in a pressure cooker. Only rice and dal require a larger quantity of water to cook properly.

Lower the heat once full pressure is reached

High heat is only needed to build pressure. Once your cooker reaches full pressure, turn the heat down — the food will continue cooking just as well, with far less fuel

Don’t leave too much empty space

A pressure cooker works most efficiently when it’s reasonably full. If you are cooking a small quantity, use a smaller cooker. Alternatively, use separators to utilise the space and cook multiple ingredients — rice, dal, and vegetables — simultaneously.

Match the flame to the cooker

If the flame creeps up the sides of the vessel, it’s too large. A well-matched flame heats only the base of the cooker, ensuring no fuel is wasted.
