White sauce

Sauce blanche

 

White sauce or sauce blanche in French is a very common sauce in French cooking. It’s quite easy to prepare and require very few limited ingredients: water (or hot liquid), butter, wheat flour, nutmeg… Anyway, it requires attention otherwised the prepration can burn or get lumps.

That white sauce is served with white meat, white fish or vegetables. It is also one of the ingredients of different recipes such as vegetable or potato gratins.

That sauce can be also the starting point for preparing many other sauces: in that case, we personalize it adding other ingredients: spices, chopped herbs, white wine.

Another version of that sauce exists with milk. In that case we call it: “sauce béchamel”. It is used in many prepration such as grilled cheese sandwich, gratins, lasagna, etc…
