Italian Giorgio Baresi, winner of the 2021 Nobel Prize in Physics, argues that cooking pasta without the stove, after boiling water, allows you to consume less energy and, in this way, saves the current situation of energy crisis.
Parisi details, in a Facebook post, that once the water starts to boil, you can add the pasta and wait for two minutes, then turn off the gas to continue cooking.
The scientist at Sapienza University in Rome calculates that “at least eight minutes of energy consumption” is saved in this way.
“The most important thing is to keep the lid on, a lot of heat is lost through evaporation. After boiling the pasta, I put the gas on the minimum, so that it boils a little without consuming. You can also try to turn it off, as suggested in this post, which is not for me, But by Alessandro Borisi Vesi, which I simply shared. Obviously, in this way, less gas is consumed and the pasta is cooked more evenly,” he says.
The debate about how to cook pasta without wasting energy is not new, with the Unione Italiana Food Association, which represents pasta manufacturers, argued a few months ago that keeping the lid on the pan during the boiling phase speeds up the cooking process and saves “up to 6% in energy emissions.” and carbon dioxide.”
The association explained that extinguishing the fire after two minutes of boiling and leaving the lid working saves energy and carbon dioxide emissions, which can reach 47%.
“With an average consumption of 23.5 kg of pasta per capita, each Italian would save up to 44.6 kWh, 13.2 kg of CO2 emissions and 69 liters of water per year,” he highlighted this correlation.
