Ingredients

Directions

Prepare

  1. Cut the calf's head into good slices, not too thin.

  3. Reduce the mixture by half over heat.

Make the hash

  1. Add the calf's head slices and ½ cup more broth, seasoning with pepper and salt.

  2. Heat through, then mix butter with flour and add to the pan, breaking it into pieces.

  3. Shake over heat until slightly thickened, adding coloring for a light brown color.

Serve

  1. Pour onto a dish and garnish with gherkin slices.

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

What each ingredient does

Calf's head
Forms the meaty body of the hash, cut into slices that hold their shape in the sauce.
Butter and flour
Mixed together, they thicken the broth into a slightly thickened sauce as they heat.
Broth
Provides the liquid base that the sauce reduces and thickens around the meat.
Vinegar
Adds acidity that sharpens the flavor and helps balance the richness of the meat.

The step that matters

Shaking the butter and flour into the pan. Flour added as lumps can clump and stay floury. Breaking the butter and flour into pieces and shaking over heat lets the starch disperse and thicken the sauce evenly.

Swap the walnut

How well each one fits the dish's main ingredients (onion, vinegar, thyme, pepper, butter, flour):

  1. Black-eyed peafits better
  2. Lentilsfits better
  3. Chestnutfits better
  4. Walnutthe original

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