The pros and cons of Passive Cooking explained by Pasta Garofalo
There’s been a lot of talk about passive cooking of pasta in the past few months.
And, as usual, we wanted to find out the truth about the matter. So we analysed the question from every point of view.
In Pastificio Lucio Garofalo’s laboratory, we experimented with the passive cooking technique on all our types of pasta (from short pasta such as Penne rigate to long pasta like Spaghetti and special pasta such as Gigantoni). We present our findings here.
FLAVOUR
We are experts on pasta, and have been for 300 years. Those who choose our pasta want a top-quality product, and this is why we feel it is our duty to report that passive cooking does not produce as good a flavour as the traditional method of cooking pasta.
The infographic below sums up the two cooking methods, traditional and passive, with instructions for both and the main pros and cons.
Not all pasta shapes produced the same results. Spaghetti respond best to cooking with the element turned off, while short pasta does not perform as well.
Top quality pasta such as ours stands out for its excellent texture, which is not the same following passive cooking.
This table shows the results of the tests we performed with Spaghetti and Penne Rigate.
Our assessment takes into consideration the 7 parameters identified by UnionFood: Cooking time specified on the package; Firmness after cooking; Separability; Presence of core; Sticky texture; Ability to absorb sauce; Taste.

SAVINGS
How much money and energy can be saved by passive cooking?
First, we need to talk about putting the lid on the pot while cooking pasta. Putting the lid on saves 30% on water consumption and 10% on energy consumption, saving about 20 grams of CO2 emissions every time you cook pasta.
Supposing you cook pasta 300 times a year, you will save 15 euros and five and a half kilograms of CO2 emissions.
In calculating the savings resulting from passive cooking, we took into account the price of natural gas and electricity in the month of October.
If you cook pasta for a family of four three hundred times a year using the passive cooking method on an induction cooker, you can save up to 60 euros a year.
But if you use a gas cooker, you save only 7 euros.
Total energy savings in one year of passive cooking are equivalent to the amount of energy required to charge a mobile phone for 15 years.
