One should always cover a pan while heating

One should always cover a pan while heating

Tradition says: "One should always cover a pan while heating".

In other words, if you heat water (or something else), it comes to the boil faster with a lid on the pan than without.

True or false? Let's try the experiment...

Step by step recipe

1 One should always cover a pan while heating : Photo of step #11 litre of water is measured and poured into a pan without the lid and put on the hob with a thermometer in it.

Starting temperature of water (and room): 70°F (19°C).
2 min.
2 One should always cover a pan while heating : Photo of step #2The heat is switched on. The water reaches 210°F (100°C) in 9 minutes and 30 seconds. 9 min.
3 One should always cover a pan while heating : Photo of step #3The hob is left to cool for about one hour, to allow it to reach room temperature again.

Another 1 litre water is put in the same pan covered with the same thermometer in it, on the same hob.

Starting temperature of water (and room): 70°F (19°C).
1 hour
4 One should always cover a pan while heating : Photo of step #4The heat is switched on. The water reaches 210°F (100°C) in 9 minutes and 27 seconds. 9 min.
5 One should always cover a pan while heating : Photo of step #5The result is shown more clearly in the diagram: the temperature of the uncovered pan in red and that of the covered pan in green.

Conclusion

False: The time difference is too small to be significant. It really doesn't matter whether the pan is covered or not.
And to drink?: We are going to heat 1 litre of water in an uncovered pan and measure the time it takes to boil , then another litre in a covered pan, heated and measured in the same way.

Comparing these times will tell us if it is really necessary to cover the pan.
