To Heighten the Colour and the Flavour of Gravies

Oven, in the book's wordsA slow oven

Ingredients

Directions

Colour and flavour

  1. Add thick mushroom pressings, soy sauce, cavice, or Harvey's sauce to gravies for colour.

  2. For flavour, add a glass of claret or port wine.

  3. Brown 1 ounce of vermicelli or rasped cocoa-nut in a small amount of butter, then stew it in the gravy for 30 to 60 minutes.

  4. Strain the mixture out.

Thicken and finish

  1. Use arrow-root, rice-flour, or browned common flour to thicken gravies instead of flour and butter.

  2. Ensure no fat is visible on the gravies before serving.

  3. If fat cannot be skimmed, let the gravy cool to congeal the fat for easy removal.

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

What each ingredient does

Thick mushroom pressings
Adds deep brown colour and savoury, earthy flavour to the gravy.
Soy sauce
Adds savoury depth and darkens the gravy's colour.
Claret or port wine
Adds body and a fruity, slightly acidic richness to the flavour.
Vermicelli or rasped cocoa-nut
Browned in butter and stewed in the gravy, it adds toasted aroma and dark colour.
Arrow-root or rice-flour or common flour
Thickens the gravy so it coats the spoon rather than running thin.

The step that matters

Strain the mixture out. Stewed vermicelli or cocoa-nut releases particles and oils into the gravy, so straining is needed to leave a smooth liquid with only the intended colour and flavour.
