White Gravy and Other Sauces

Ingredients

Directions

Prepare the juices

Let the meat sweat without browning and prick it to release juices.
When the knuckle is cooked, skim the sauce and strain it through a fine sieve.

Thicken the sauce

Boil the sauce until reduced, then add roux blanche to achieve a thick consistency.
Skim and boil again, stirring continuously until smooth.
Cool the sauce by lifting it in a spoon and letting it fall.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Meat juices: Provide the base flavour and body of the gravy.
Roux blanche: Thickens the sauce as its starch swells when heated in liquid.

The step that matters

Adding the roux blanche and stirring until smooth. Roux thickens only as its starch swells in hot liquid. Adding it to a sauce that is not yet reduced can leave it too thin or cause lumps, so stir continuously while it simmers to keep the texture smooth.
