1/7
Pressure cooker cooks food in a closed space using steam pressure. Open cooking means cooking in normal utensils without pressure. Both are common in kitchens, but they work differently.
2/7
Pressure cooker cooks food much faster. Dal, rice, and vegetables takes less time in it. Open cooking usually takes longer, so more gas is used.
3/7
Since cooking time is less, pressure cooker uses less LPG. In open cooking, flame stays on for longer time. This is why gas consumption becomes higher.
4/7
Pressure cooker traps heat and steam inside. Very less heat gets wasted during cooking. In open cooking, heat keeps escaping again and again.
5/7
Pressure cooking helps in keeping nutrients better. Food cooks faster so it is not over exposed to heat. Open cooking sometimes makes food overcooked.
6/7
Open cooking is better for frying and some curries. It gives more control on taste and texture. Not every dish can be cooked in pressure cooker.
7/7
If you want to save LPG, pressure cooker is better option. It cooks faster and uses less gas. But using both methods smartly will give the best results.
