When should I change my knife?


When should I change my knife?
I already spoke to you in a previous post about knives, those without which nothing is possible (or almost) in the kitchen, so I'm going to come back to them a bit and try to answer the question "When should I change my knife?

When should I change my knife?
You may remember how important it is to pay a lot of money for your knives, and to choose models with a stainless steel blade, a handle made of a composite material often called "plastic", etc. This is still true, and I dwell a little on the blade, which being made of steel, with time dulls, sharpens and must therefore be regularly sharpened. This is always true, and I dwell a little on the blade, which being steel, with time dulls, de-sharpens and must therefore be regularly sharpened.

The best way to do this is to use a sharpener, and in an elegant gesture (but unfortunately not easy to catch) you sharpen the blade again. To make a long story short, you should always have razor-sharp knives, it's always much more pleasant to cook with.

Let's come back to this knife sharpening, it turns out that in the gesture of sharpening, one naturally accentuates one's effort on the middle-lower part of the knife blade, and therefore it is there that the wear will be the fastest. This wear can be seen over time, it creates in the blade of the knife, very slowly, a small hollow, a slight curvature, which you can see on this photo (red arrow):

used knife



This hollow, if visible, is a sign that your knife is at the end of its life in "kitchen" mode: You will find it difficult to sharpen it, more and more, so it will cut less well, and will not be ideal for cooking.

To make a comparison, see these 2 knives side by side:

worn knife vs. new knife



The top one is new, the bottom one has lived well, note the hollow of the blade at the bottom, and the nice rounding of the top one.

It's time to change the bottom one, of course you shouldn't throw it away, but use it for something else than cooking (garden, DIY, ?) or recycle it.

Well, it's not always easy, we are often attached to our tools, that we have well in hand, but it is necessary to take the step, the old knives even if they have a sentimental value, can become a brake to your good cooking.


To sum up: When the blade of your knife starts to get hollow, it is time to think about changing it.

Perhaps you too cook by consulting your recipe on a tablet or phone, and putting it down on your worktop? It's practical, but not the best solution. Here's a look at how you can make an inexpensive, almost universal stand.

Pre-calibrated pastry dough
Pre-calibrated pastry dough
When making pie dough (shortbread, shortcrust, sweet...), it's always a good idea to make a lot at once, and then divide it into pieces, which you can freeze. I've already pointed out the mistake not to make, which is to form a ball before freezing. It's difficult to roll out afterwards because...

We often read in a recipe where a pastry is put into a mould that, just before pouring, the mould should be buttered or greased. But what's the difference between these 2 terms?

Getting out of the fridge early
Getting out of the fridge early
Very often when you're cooking, you need to take food or preparations out of the fridge, to use them in the recipe in progress. There's nothing tricky about this: you just take them out of the fridge and use them, usually immediately, in the recipe. But is this really a good method?

When you look at a bakery from the outside, you naturally think that in the bakery, the bakers make the bread, and in the laboratory, the pastry chefs make the cakes. It's very often like that, with each of these professions having quite different ways of working, but sometimes there's also one...

Very often in pastry making, you have to roll out a pastry before using it for a pie or another dessert. At home, of course, you get out your rolling pin and simply roll it out. Is there a way to get an evenly rolled out dough? That's what we will see in this article.

Preserving egg yolks
If you're using only the egg whites in a recipe (such as meringues ), you'll need to store the yolks until you're ready to use them again. There's nothing very complicated about this in principle - all you have to do is chill them, but there are a few pitfalls to be avoided in practice.

What is as good and simple as pasta? Not much, I think, and it's so easy to prepare: boiling water, salted (or not, depending on your taste), a few minutes of boiling and it's ready.
