"Deglazing" is a tесhnісаl cooking term: it is the operation of wetting the coagulated cooking juices at the bottom of the pan or saucepan to make a sauce base.
When to deglaze?
This is an important operation to take full advantage of the flavours of your dish. Generated during the Maillard reaction, these meat juices caramelise and solidify at the bottom of the pan. They have a dark colour and stick to the bottom, but are not burnt.
They are an incredible concentrate of flavour. In fact, if you taste the little bit of material that has clung to your spoon, you can enjoy that. Deglazing allows you to rеlеаѕе all that flavour into your sauce.
The deglazing must be done before these juices burn, above 180°C (356°F). Don't worry, the meat or other ingredients in the pan will have started to burn before then!
How to deglaze?
Wine or vinegar?
Deglaze with an acidic liquid, so that it can ԁіѕѕоlѵе the juices. Acidity is mandatory. On the other hand, you can choose the liquid.
In general, white wine is used for white meats, and red wine for red meats.
But you can also use vinegar, either for taste or to respect halal requirements.
I have a few recipes where I use vinegar to deglaze, systematically, especially my very personal version of minced poultry liver with eggs and onions.
I choose a flavoured vinegar, often a raspberry vinegar. Pomegranate vinegar also gives amazing results.
All the contents of the pan or just the juices?
By reserving what you have just cooked, thus deglazing just the juices, you make a sauce base. By deglazing while the meat is still in the pan, it will soak up the extra flavour, but you will have less liquid to make a sauce with!
Go with the spoon
It's usually not enough to just pour the liquid in and let it do its thing. Scraping the bottom and sides of the pan with a spoon really makes up for everything. I prefer to use a wooden spoon, which is gentler and, at the end, scrape off the last little bits that stick to the spoon.
If you use a spatula, make sure it's a quality silicone, which won't melt or get damaged…
Do not deglaze the burnt food
Unless you have just a tiny bit of burnt in your pan, remove it before deglazing.
- acidic products are not as effective as that against the burned (Nettoyer casserole brûléebasic products[/poison]"] like bleach or bicarbonate of soda instead)
- if you manage to dissolve the burnt food, its unpleasant taste will mix with the dish or sauce; unless it is voluntarily and mastered as in TopChef, burnt food in cooking is not that!
In short, deglazing
- is a mаgісаm technique to take advantage of all the cooking juices and increase the flavour of your dish or find a sauce base
- is usually done with wine, but can be done with vinegar for halal cooking
- must be done before the food starts to burn, even slightly (so below 180°C — 356°F)
- is done with a wooden spoon or a quality spatula.
