Almost every Indian kitchen has a pressure cooker, and many use it more than once a day. A good one lasts 10 years or more, so it’s worth choosing carefully.
1. Material
| Material | Pros | Cons | Induction? |
|---|---|---|---|
| Aluminium | Light, cheap, heats quickly | Can react with acidic food; dents and discolours; shorter life | Only with a special induction base |
| Hard-anodised aluminium | Non-reactive, scratch-resistant surface; heats quickly and evenly | Costs more; usually not dishwasher-safe; needs gentle cleaning | Only with a special induction base |
| Stainless steel | Very durable, non-reactive, easy to clean, keeps its looks | Heavier, costs more; heats unevenly unless it has a sandwich base | Yes, with a magnetic sandwich base |
Sandwich or tri-ply base: a layer of aluminium or copper inside a steel base, which spreads the heat. Without it, a steel cooker can scorch dal or rice at the bottom. Look for it on any stainless steel cooker.
2. Size
| Household | Suggested size | Typical use |
|---|---|---|
| 1–2 people | 2–3 L | Dal, a small pot of rice, vegetables |
| 3–5 people | 3–5 L | Everyday dal, rice, rajma, chole |
| 5+ people, or cooking for guests | 5 L and above | Biryani, large batches, meat |
The usable volume is less than the size on the box, because you can’t fill a cooker to the top (see the safety section). If you cook dal and rice every day, two cookers (a small and a medium one) are often more practical than one big one.
3. Inner lid or outer lid
- Inner lid: the lid goes inside the cooker and pressure seals it from inside, so it physically can’t be opened while there’s pressure in it. It takes some practice to fit, and the mouth is slightly narrower.
- Outer lid: sits on top like a normal lid and locks with a twist. It’s easier to use and clean, with a wider mouth for stirring and serving.
Both are safe when they meet the BIS standard and are used properly. Choose the one you find easier.
4. Safety features to check
- ISI mark: pressure cookers must meet BIS standard IS 2347 and carry the ISI mark. Don’t buy one without it.
- Safety valve: a second release point (often a metal or rubber plug) that lets steam out if the main vent gets blocked.
- Gasket release system: some cookers let the gasket push out through a slot under too much pressure, instead of the lid failing.
- Solid, heat-resistant handles fixed with strong screws, plus a helper handle on bigger cookers.
- Spare parts: check that gaskets, whistles and safety valves for the model are easy to buy.
5. Safety habits
- Never fill above two-thirds, or half for dal, rice and other food that foams or expands.
- Always add enough water for the recipe. Never heat an empty cooker.
- Check the vent tube is clear before every use. Hold the lid up to the light.
- Never force the lid open. Let the pressure drop on its own, or lift the whistle carefully with a spoon, away from your face.
- Replace the gasket when it’s hard, cracked or leaking, and the safety valve if it’s damaged or has ever blown. Use original parts.
- Keep the flame under the cooker, not licking up the sides, where it can damage the handles.
6. Cleaning and care
- Aluminium: wash with soap; a little tamarind or lemon brings back the shine. Avoid storing sour food in it.
- Hard-anodised: use only a soft sponge and mild soap; no harsh scrubbers.
- Stainless steel: you can scrub it. Soak burnt-on food with baking soda and water first.
- Gasket: wash it after each use, dry it, and store it separately or loosely so it keeps its shape.
Bottom line
Buy the right size, choose stainless steel with a sandwich base for longevity (or hard-anodised for faster cooking on gas), check for the ISI mark, and follow the safety habits every single time.
Frequently asked questions
Which is better: a steel or aluminium pressure cooker?
Stainless steel lasts longer, doesn't react with acidic food like tomatoes and tamarind, and with a sandwich base works on induction. Aluminium is lighter, cheaper and heats faster, but it can react with acidic food and wears over time. Hard-anodised aluminium sits in between.
What size pressure cooker do I need?
As a rough guide: 2 to 3 litres for one or two people, 3 to 5 litres for a family of three to five, and 5 litres or more for larger families. Many homes have two: a small one for dal and a large one for rice and bigger batches.
Is the ISI mark compulsory on pressure cookers?
Yes. Pressure cookers sold in India must meet the BIS standard (IS 2347) and carry the ISI mark under a government quality control order. Don't buy one without it, including online.
How often should I replace the gasket?
When it's hard, cracked, stretched or lets steam escape around the rim. For a cooker used daily, that's often about once a year. Always use the brand's original gasket for your model.
