Which of these is a mixture of fat and flour used in making sauces?

Bebeto, the question really isn't misleading. Béchamel is made of a roux + milk, so the obvious answer is roux. Would you try to argue that cake would be a correct answer too as it is made of flour, fat, milk, egg and sugar.

Bebeto, bechamel is one of the sauces which roux is used to make. The question is not misleading or confusing.

In Creole cousine in Lousiana my grandmother taught me how to make a roux with butter and flour.

I love this game!!!

Player #7719043, My Mom made roux often but we didn't know it was called roux!

The darker you let it become depends on what is the base for.
