We tested 10 common cooking tips and here are the results!
Share on Facebook

With the Internet, we are bombarded with tips and tricks to make our lives easier in many areas, and cooking tips are no exception. We see, among other things, a lot of advice that our grandmothers passed on to our parents and that they then passed to us. 

But do all of these cooking tips really work? The team of the Sympa website tested 10 of the most common and popular tricks, in order to see if they are really effective or if they are myths. 

Are you using any of these following tips?

1. To make dough softer,  mix vinegar with soda.


To demonstrate that this is a myth, there is no need to bake bread. Let us remember our chemistry lessons!

If you want soda to act as a baking powder, it also needs an acidic element.

But if you mix it in vinegar, carbon dioxide is released and it is said to make the dough softer. The problem: the carbon dioxide evaporates before being incorporated into the dough...

You must mix the soda with the dry ingredients and the acidic elements with the other liquids. 

It is much more effective to use sour cream or lemon juice as the acidic element. Or simply just buy commercial yeast.

In conclusion: this advice is a myth that we must stop sharing.

2. To easily remove an eggshell after cooking, immerse it in cold water.

Many grandmothers encouraged to immerse hard-boiled eggs in cold water to easily remove eggshells. Unfortunately, this technique is not enough.

Having cooked thousands of eggs for years, chef Kenji López-Alt would have found the perfect cooking technique. According to him, this consists of immersing the eggs in boiling water and not cold water!

We did the test and indeed, the eggs are much easier to peel!

However, eggshells can break with the difference in temperature.


Here are other secrets about hard boiled eggs:

• The fresher the egg, the more difficult it is to remove it from its shell.

• If you put cooked eggs in water containing ice cubes for at least 15 minutes and then peel them under a cold stream of water, things will be easier.

• Chef Kenji ensures that steaming is the best way to prevent the eggs from breaking down.

In conclusion: It works, if we adapt the classic rules.

3. To make it easier to clean a dirty pan, boil a saline solution in it.


Old cookbooks advised the queens of the household to clean burnt pans by adding water and salt to them and bringing them to a boil.

But after a test, it didn't work. The salt mixture is not good for stainless steel.

It's best to soak the pan in lukewarm water and leave it like that overnight. In the morning, it will be easier to clean it, even if it is badly burned.

In conclusion: this method is useless.

4. In order not to have an unpleasant fishy smell on hands and dishes, they should be rinsed in cold water and then washed with vinegar or lemon.


The smell of fish can be stubborn and even strong soaps may not be able to overcome it. Good news, this advice from grandma is good!

Rinse your hands or the dish with water and then rub with lemon juice. Vinegar can also help you solve this smelly problem.

Conclusion: Yes, it works!

5. The cheese should be stored in paper towels, not plastic wrap, so that it does not dry out.

Sympa tested this advice by wrapping a piece of cheese in "saran wrap" and another in paper towel and leaving the two in the refrigerator for 3 days.

It turned out that the cheese wrapped in paper towel became dry, unlike the piece deposited in the plastic wrap, which remained quite fresh.

So in conclusion: this advice does not work.


6. To avoid crying while cutting an onion, the knife should be soaked in cold water.


Everybody people hate cutting onions because it makes them cry! The advice to frequently dip the knife in water is therefore popular.

The stuff works in general, but it all depends on the onion and the sensitivity of the eyes of the person who cuts it. Without forgetting that wetting a knife all the time is not super practical!

In conclusion, it works, but it is not magic.

7. Peel cooked potatoes easily by soaking them in cold water.


Boiled potatoes are not always easy to peel. This is because we usually peel them right after taking them out of their pan. The skin always sticks to our fingers.

To make the process easier, it is recommended to place the boiled potatoes in cold water for a few minutes before proceeding. Our mothers were right, it works!

The potatoes will cool quickly and the skin will be very easy to remove.

The catch? The potatoes then become slightly pasty, which does not please everyone. Up to you!

So, in conclusion, it works.

8. To quickly cool a hot drink, it should be placed in a container with ice and salt.


It’s a basic physics principle. If you add salt to the ice, it melts a little and its temperature drops. This mixture can cool a hot drink in minutes.

In conclusion: it works.

9. For an onion not to be bitter, blanched with boiling water.


A dish that contains bitter onions is not pleasant. You can then place the onions in a small container and pour boiling water over them. Then, wait 1 to 2 minutes and take the onions out of the water. After verification, they really lose their bitterness.

Conclusion: it works!

10. To prevent avocados from darkening, store them with an onion.

When half an avocado is left in the refrigerator for more than a day, it turns black very quickly. To avoid this, some people tell us to store the avocado with a piece of onion.

Disappointment: in addition to not working, this method leaves a slight onion taste to the avocado.

Conclusion: it does not work.


There you go, proof that mom wasn't always right!
