Directions

Make the gravy

  1. Make the gravy separately by boiling bones, trimmings, vegetables, herbs, pepper, and salt for at least 1 hour.

  2. Fry a chopped onion in butter or dripping until brown.

  3. Mix flour with stock and pour into the saucepan, bringing it to a boil.

  4. Add any desired flavorings like catsup, anchovy, lemon, or nutmeg.

Finish and serve

  1. Strain the gravy, warm the meat, and serve with fried or toasted bread slices.

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

What each ingredient does

Meat
Is the main component, warmed through in the finished gravy and served with bread.
Butter or dripping
Provides fat for frying the onion, adding richness and browning flavour.
Flour
Thickens the stock as its starch swells when heated, giving the gravy body.
Stock
Forms the liquid base of the gravy, carrying the flavour of the dish.
Onion
Browns in the fat, adding sweetness and savoury aroma to the gravy.

The step that matters

Mixing the flour with the stock. Stir the flour into the stock thoroughly before adding it to the pan, so it disperses without lumps. Starch thickens the liquid only as it heats, so the gravy should be brought to a boil and kept there to fully thicken.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (meat, butter, flour, onion, sauce, anchovy, nutmeg):

  1. Avocadofits better
  2. Raisinfits about as well
  3. Lemonthe original
  4. Coconutfits about as well

Fit is the average pairing score against meat, butter, flour, onion, sauce, anchovy, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
