Should I believe my oven?


Should I believe my oven?
Can you really trust your oven? This is an important question as we are always tempted to take the temperature indicated as gospel truth and, unfortunately, this is rarely very precise.

Should I believe my oven?
When I set my oven to 200°C, is it really at that temperature? The actual temperature can be measured easily if you have an accurate thermometer.

To check my own oven (a “De Dietrich” model UMP501), I placed the probe of the thermometer in the oven, closed the door, set it to 200°C and noted the temperature at 30 second intervals over 20 minutes.

Ideally, of course, the oven should heat up rapidly to exactly 200°C, then stay at this temperature until I open the door to put the food in, or until I turn it off. Unfortunately, the reality is dramatically different. Here is the temperature curve recorded:

oven temperature


From this graph we can note that:

1) The oven takes 10 minutes to reach 200°. So far, so good.
2) It beeps to tell me that it has reached 200° when, in fact, it is only at 191°, which is not so good.
3) Although it is supposed to stop heating at 200°C, it goes up to 217° before coming back down to 186°, and from then on it varies 10 or 20° around the set temperature, which is far from ideal.

These variations are significant but, fortunately, not the end of the world for most recipes. A little hotter or cooler doesn't make that much difference, and can be compensated by a slightly shorter or longer cooking time.

But take care, even so, with recipes that require a precise temperature, such as macarons or foie gras. For these, it is a good idea to measure the oven temperature when it indicates that it is at the right temperature, then adapt the recipe accordingly.

This is somewhat disappointing, as my oven was quite expensive at the time, and the salesman promised me an oven that had “precise temperature control” . But then, when it comes to selling, they always promise the moon.

So, in the end, in answer to the question “Should I trust my oven?” the reply is definitely: no, you should not trust your oven. Instead, you should measure and calibrate it beforehand to know how it really performs.

And then, we're talking here about an electric oven. Just imagine what's involved with a gas oven…

A drizzle of olive oil
Often in a recipe, you have to "baste" vegetables, for example, before sending them to the oven. What the author means by this is that you need to put oil on top of the vegetables to cook them in the oven. Typically, we just quickly drizzle oil over the vegetables, hoping not to miss any, but...

Cherry clafoutis, with or without pits?
When it comes to cherry clafoutis recipes, there's often a camp of those who argue that you absolutely have to leave the stones in because it tastes better, and the other camp (myself included) who prefer cherries without stones, which makes a much more pleasant clafoutis to eat. But is it true...

Should potatoes be washed twice?
Let's say you have to make a recipe that includes potatoes, let's say sliced, you'll most likely proceed as follows: Peel the potatoes, wash them, slice them, wash them again, pat them dry and add them to your recipe. But there's a "but": depending on the recipe, the second washing may be a bad...

What is the difference between bakery and patisserie?
This is a question that you may well have asked yourself and which I will attempt to answer. In France the two trades of "boulangerie" (bakery) and "pâtisserie" (patisserie and confectionery) have always been quite distinct, but where exactly do the boundaries lie? .
