Can the duration of the whistle determine if food inside a pressure cooker is cooked
Building upon this question, I was wondering if the duration of the whistle can be used to determine if the food inside a pressure cooker is cooked.
As suggested by a couple of answers in the question referenced above, certain things do not work:
- The manufacture recommended two whistles in India, but in Germany it takes 6-7.
- The aroma can not always help, for example in case of making plain rice.
I have been trying to observe this event for the past few days. As the time increases, the duration of the whistle decreases (I have not measured it per se...just an observation). Has anyone else observed this. If this observation is actually correct , can this be scientifically explained?

The short answer to that question is no. The whistling sound is just a signal to reduce the heat.
Here's an excerpt from the Hawkins Pressure Cooker Operating Guide:
After the pressure regulator is placed on the steam vent, there is at first a very low hissing sound of steam from the pressure regulator. Then steam emission increases to full force and the pressure regulator lifts with a whistling sound. The cooker is now at full operating pressure. This is the point at which to reduce heat and start timing the recipe.
So, the timing or frequency of whistles is a function of how hot the pressure cooker is at any given time, and most importantly, a warning to turn down your stove, so that a catastrophe does not ensue.
As the Hawkins manual explains, start timing your recipe once the cooker has reached operating pressure. The actual timing of course, will vary, depending on the particular food you're cooking.

How do you know when food is cooked in a pressure cooker?
The pressure cooker starts the countdown time when the level of pressure you chose is reached. It then beeps when done, telling you your food is ready. Bear in mind that high altitude means longer cooking times.How do you know when a pressure cooker has reached pressure?
When the jiggle top pressure cooker reaches \u201chigh pressure,\u201d the pressure regulator (toggle) will whistle to release steam. This is how you know you have reached high pressure. After the first whistle, turn down the temperature to medium and continue to cook for the amount of time determined by the recipe.How long does it take for pressure cooker to whistle?
It takes 6\u20138 minutes to start whistling. You can wait for 4 whistles and switch off the stove. In about 10 minutes cooker cools down on its own.Can you count cooker whistle?
Cooker Whistle Counter is an application which uses machine learning to count the number of whistles heard from the pressure cooker and trigger the alarm when the count is reached.How does a Pressure Cooker Work? - Science for Kids | Educational Videos by Mocomi Kids

Answer 2
I have the same problem, as Indian recipes often specify the number of whistles - like 7 or 12. Based on one recipe, I have found that what was said to be 7 whistles took me 80 minutes of slow cooking - an even steady boil. That makes one whistle about 11.5 minutes of standard slow boiling.
Answer 3
As far as the indian style pressure cooker, with a seperate weight, the 'number of whistles' typically isn't a standard. It depends on the size, specific weight of the weight, and what you're cooking. Typically, the number of whistles for a specific recipe tends to depend on the specific cooker and you'd quite often hear "4 whistles if its the little cooker, 3 if its the large one"
You'd really want to get familiar with your cooker and experiment a bit, rather than 'assuming' that they all have the same cook-time and pressure.
Answer 4
Whistles is very specific to Indian pressure cookers and even then it is not an accurate way specify a recipe. In the west we use time, pressure and release method; such as black beans take 25 minutes at full pressure with natural release. In India, a recipe would say 2-3 whistles. As a conversion, take the mid-point which in this case would be 2.5 whilstles X by 10 minutes = 25 minutes. Though most Indian cooks know how their cooker performs and how to estimate the right cooking time for different ingredients. Chickpeas take about 55 minutes in a western pressure cooker. Most indian recipes will say 5-6 whistles. I have a chart in one of my cookbooks that tells me times for different ingrients -- you'll start to see the correlation as you cook.
