Roux
Roux () is flour and fat cooked together and used to thicken sauces. Roux is typically made from equal parts of flour and fat by weight. The flour is added to the melted fat or oil on the stove top, blended until smooth, and cooked to the desired level of brownness. Butter, vegetable oils, bacon drippings or lard are commonly used fats. Roux is used as a thickening agent for gravy, sauces, soups and stews. It provides the base for a dish, and other ingredients are added after the roux is complete.
List of Humanx Commonwealth races
Visually, the Thranx are an insectoid race resembling large praying mantises, about 1.5 meters long when on all six legs. Chitin color differs between males and females, being blue for the males and aquamarine for females, deepening to purple in old age. If a Thranx is in a profession that offers a great deal of stress premature purpling of the chitin may be visible, as is the case with Major Orvenalix in "Bloodhype". Their exoskeletons are able to withstand most common accidents, making accidental cuts or scrapes unlikely, but if their chitin is breached they bleed far more profusely than their human allies. They can also mend broken or cut chitin with a false chitin substitute.
