To Roast Calf's Liver

Ingredients

Directions

The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare and roast

  1. Preheat your oven to 350°F (175°C).

  2. If desired, lard the liver with bacon or wrap it in well-buttered paper.

  3. Roast the liver for 1 to 1¼ hours, basting constantly.

  4. Remove the paper and froth the liver for 10 to 15 minutes before it's done.

Make the gravy and serve

  1. For gravy, trim small bits of liver, flour them, and fry with sliced onion.

  2. Add 1/2 pint of water, peppercorns, herbs, and season with salt and lemon juice.

  3. Serve with a piquant sauce, such as poivrade or brown eschalot, and good gravy.

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

What each ingredient does

Calf's liver
Forms the main body of the dish, cooking to a tender, meaty texture.
Butter
Enriches the liver with fat and helps it brown while roasting.
Bacon
Adds fat and savoury flavour when larded into the liver as it roasts.
Flour
Coats the liver pieces so they brown and thicken the gravy.
Onion
Adds sweetness and savoury depth to the gravy as it fries and softens.

The step that matters

Basting constantly while roasting. Liver is lean and dries out quickly in dry oven heat. Frequent basting with fat keeps the surface moist and helps it cook evenly and stay tender rather than tough.

Swap the onion

The recipe marks onion as optional. How well each one fits the dish's main ingredients (liver, pepper, butter, vinegar, flour, lemon):

  1. Shallotfits better
  2. Mustardfits better
  3. Capsicumfits better
  4. Onionthe original

Fit is the average pairing score against liver, pepper, butter, vinegar, flour, lemon. Candidates are from the same food group and used in at least 100 recipes.
