French White Sauce
Ingredients
Directions
Make the stock
Combine ½ pint of white stock, a small bunch of savoury herbs, and a little salt in a stewpan.
Boil the mixture for a few minutes to extract the herb flavor.
Strain the mixture.
Return the strained stock to the heat and boil until reduced by half.
Thicken and finish
Mix 1 teaspoon of arrowroot with 1 tablespoon of cream until smooth.
Stir the arrowroot mixture into the stock in the stewpan.
Let the sauce simmer for about 15 minutes over low heat.
If the sauce is too thin, stir over high heat until thickened.

What each ingredient does
- White stock
- Forms the liquid base that the sauce is built on and reduced to concentrate its flavor.
- Arrowroot
- Thickens the sauce as its starch swells in the hot liquid, giving a glossy, smooth texture.
- Cream
- Adds richness and body, softening the sauce's flavor and mouthfeel.
The step that matters
Adding the arrowroot mixture. Arrowroot must be mixed smooth in cold cream first and then stirred into hot stock. Added directly, it clumps and cannot thicken evenly. Starch thickens only when heated, so the sauce must be kept hot long enough for it to swell fully.
