Pressure Cooker: €565 Savings in 15 Years for €20 Investment
A calculation circulating online claims that spending €20 more on a pressure cooker instead of a conventional pot returns €564.85 over fifteen years. The thesis relies on the premise that a pressure cooker consumes 70% less energy than a traditional one, reducing a 50-minute stew cooked on high heat to just 9 minutes on medium heat. Based on this, the average annual saving is estimated at €38.99. This figure isn't arbitrary: the average Spanish household spends €990 annually on electricity, with 9.3% allocated to cooking, resulting in approximately €111.40 per year for stove energy including VAT. If half of all stews are made using a pressure cooker, the saving amounts to €38.99 per year. Here lies the appeal: a €20 extra cost compared to a normal pot, amortized in just 187 days.
The Calculation Promising 50 Times More Returns Than Stocks
The comparison with financial investment is explicit. Putting €1,000 into stocks and waiting fifteen years to receive €564.85 in dividends is, according to this approach, a poor move compared to investing €20 in a pressure cooker and letting habit do the rest. The ratio cited is 50 times more profitable. The calculation assumes a 15-year lifespan for the utensil, without adjusting for inflation or rising electricity prices. In other words, it represents the most favorable possible scenario.
The first sustancia ilegal in the discussion concerns the baseline expenditure. Some argue that €990 in annual electricity costs is a statistical aberration, as it includes homes with electric heating and does not represent the average user. Against this figure, real consumption testimonies emerge of €150 per year in electricity, specifically for those using butane gas for cooking. In this case, the average hides two distinct realities.
Gas Cooking, Butane, and Bills That Don't Add Up
The second issue relates to tariffs. Part of the analysis argues that savings should be calculated based on kilowatt-hours consumed, not the total bill, because fixed charges, contracted power capacity, tolls, and taxes do not decrease when using a pressure cooker. This nuance is correct and dismantles the headline's simplicity. However, it is also true that electricity consumption statistics refer to kilowatts, not euros, so the €38.99 saving applies only to the variable portion. Fixed costs remain the same whether you use a pressure cooker or not.
A detail emerges here that complicates matters: some people cook with butane and heat water with the same heater, yet still pay €150 per year for electricity. The pressure cooker calculation then becomes unstable for this user profile, as gas usage is excluded from the electrical equation. For those who cook with electric hobs, the saving is real. For those who cook with gas, the energy saving exists but is reflected in a different bill.
Do You Lose Vitamins When Cooking Under Pressure?
The third point is nutritional. Some participants claim that pressure cookers raise temperatures above 100 degrees Celsius, destroying vitamins and nutrients. The technical response in the discussion contradicts this: the shorter the cooking time and the less liquid added, the fewer vitamins are lost. Water in a pressure cooker reaches between 120 and 130 degrees, but for much less time, minimizing the destruction of sensitive nutrients. The debate remains open, but the counter-nutritional argument is nuanced.
Real Risks: Valves, Explosions, and Precautions
The fourth aspect is safety. There are accounts of pressure cookers exploding. One describes a kitchen resembling an alien nest after the utensil burst, fortunately with no one present in the room at the time. The repeated recommendation is to check valves before each use, not fill the pot more than three fingers below the rim, and buy a larger capacity model than needed to avoid overfilling. Modern pressure cookers have multiple safety valves, but this does not eliminate the need for maintenance.
Slow Fire Flavor Versus Estimulante ilegal
The fifth point concerns taste. Part of the discussion defends that a fifteen-minute broth in a pressure cooker is "donkey urine" compared to one made slowly over low heat. Others respond that it depends on the dish: for boiling potatoes and carrots for Russian salad, tenderizing tough meats like shank, making fish fumet, or cooking white rice, the pressure cooker not only saves time but yields better results. The debate isn't about whether to use a pressure cooker, but which dishes benefit from it and which do not.
The conclusion of the original calculation leaves a figure inviting irony: if €20 yields €564.85 in fifteen years, buying a thousand pressure cookers at €80 each and saving €40 annually per unit would generate €40,000 in profit. Formulated this way, the proposal is absurd. But the original calculation didn't speak of a thousand pots. It spoke of one. And of a habit.
