For those of us at home trying to conserve our cents while cooking pasta, is Parisis technique truly economical? And does it truly taste that bad? Inspired by the idea of conserving some cash, trainees Mia and Ross at Nottingham Trent University required to the kitchen to prepare pasta in various ways, assisting to choose apart the tangled hairs of this question.
So it was barely surprising that, when a Nobel Prize-winning Italian physicist weighed in with advice about how to cook pasta perfectly which appeared to overthrow whatever the nations cooks had actually been carrying out in the kitchen for centuries, it caused an almighty row.
In reaction, Michelin-starred chef Antonello Colonna declared this method makes the pasta rubbery, and that it could never ever be served in a top quality dining establishment such as his own. The controversy quickly spilled over into the media, with a number of food and science heavyweights contributing.
Italians are notoriously– and understandably– protective of their food, as regular arguments about the appropriate garnishes for pizza or the appropriate pasta to utilize with a Bolognese ragu will testify.
Professor Giorgio Parisi– who won the 2021 physics Nobel for “the discovery of the interaction of disorder and fluctuations in physical systems from atomic to planetary scales”– suggested that turning off the heat midway through cooking pasta, then covering with a lid and waiting for the residual heat in the water to end up the job, can help in reducing the cost of cooking pasta.
What takes place when you cook pasta?
At todays costs, the cost of cooking dried pasta on a ceramic hob can be found in at 12.7 p per serving, an induction hob at 10.6 p, and a gas hob at 7p. So provided the UKs love of pasta, with on typical everyone consuming one portion per week, we are investing ₤ 4,690,000 a week on cooking pasta.
The graphic programs that the second-largest energy requirement is from bringing the water to a boil. Once again, there is another conserving to be made here.
The basic cooking technique plunges 100g pasta into 1 litre of boiling water for 10 to 12 minutes, depending on its density. The breakdown of energy use is illustrated in the graphic below, which can be converted into a total cost utilizing information on the cost of energy and the effectiveness of the stove.

It is clear from the graphic that around 60% of the energy is utilized to keep the water boiling. Anything that can be done to reduce the cooking time would have a substantial impact on the total expense. Parisis approach of switching off the hob midway and allowing the pasta to prepare in the residual heat will halve the cooking cost, a conserving of around 3p. This approach will be even more reliable on ceramic hobs as unlike gas and induction, they are slow to cool off.
Scientists, bloggers and chefs report that the quality of prepared pasta is unaffected by significantly decreasing the amount of water. Starch is launched during cooking and if there is insufficient water the concentration develops up, leaving clumps of unevenly prepared pasta– although regular stirring of the pot may well improve matters.
It ends up that the granules of protein in pasta dissolve above 80ºC, so there is no need to bring the pan to a “rolling boil” at 100ºC, as is frequently encouraged. Mild simmering is sufficient to cook the pasta totally, supplying an extra conserving of around 0.5 p.
We also examined using a microwave to heat up the pre-soaked pasta. Microwaves are really efficient at heating water, but in our experiments this produced the worst pasta of all. Absolutely not one to attempt in your home.
Nevertheless, by separating the processes of rehydration and heating, it is possible to lower the cost even further. Dried pasta can be completely rehydrated by pre-soaking it in cold water for two hours. This is a procedure that requires no energy at all and saves an additional 3p.
When we cook pasta, the very first thing to ask is what actually occurs. In the case of dried pasta, there are really two processes that generally happen in parallel. First of all, water permeates the pasta, rehydrating and softening it within ten minutes in boiling water. Second of all, the pasta warms up, causing the proteins to expand and become edible.
How to do it– and save money
The author would like to thanks his trainees Mia London and Ross Broadhurst for their support in compiling this research study.
The reward for the most effective technique of cooking dried pasta is to pre-soak it in cold water before including it to a pan of simmering water or sauce for one to 2 minutes. Keeping a cover on the pan is another easy thing you can do. Including salt, while making minimal distinction to the boiling point, does substantially improve the taste.
We arent all Michelin-starred chefs or Nobel Prize-winning physicists, however we can all make a difference in the method we cook to lower energy costs while still producing great-tasting food. Now its up to you to try out these methods up until you find a mix that makes your cooking more affordable while likewise saving your pennes.

Water permeates the pasta, rehydrating and softening it within 10 minutes in boiling water. The pasta then needs to be dropped into boiling water to heat it through– and there are even more savings to be made here too. Chefs, scientists and bloggers report that the quality of prepared pasta is untouched by significantly minimizing the quantity of water. Starch is launched throughout cooking and if there is insufficient water the concentration builds up, leaving clumps of unevenly cooked pasta– although regular stirring of the pot might well enhance matters.
