White sauce with a deliberate raw-flour taste

A local Chinese restaurant serves what they call Portuguese Chicken: a small casserole dish with a bed of rice, pieces of crispy-fried chicken, sauce, and a sprinkling of (Parmesan?) cheese, lightly browned in a hot oven or broiler.

The sauce is like a basic white-sauce, but yellow colored (I suspect turmeric), but rather than the usual creamy flour/butter taste, while it is still smooth and creamy, it has a noticeable raw flour flavour.

That raw flour taste actually goes quite well with this dish.

Is it simply under-cooked, or is there a special technique or name for this kind of sauce?

A blond roux has a slightly nuttier flavor as the flour is toasted together with the oil or fat. It still thickens recipes and is great for sauces, bisques, creamy soups, and creole gumbo.

How do you make sauce not taste like flour?

Make a corn starch paste instead of the flour paste and you won't have the pasty flour flavor. Corn starch clumps just like flour if you just toss it in the hot mixture, so as with flour, make the smooth paste first before adding it in the pan.
