Ox Heart Roasted

Ingredients

Directions

The book gives no oven temperature. The 400°F (200°C) in the steps was added when the recipe was transcribed, as a starting point.

Prepare

  1. Wash and wipe the heart thoroughly.

  2. Fill the heart with stuffing as for a fillet of veal.

  3. Tie a piece of veal caul over the top.

Roast and finish

  1. Roast gently for 1.5 hours.

  2. Five minutes before it's done, increase the heat to 400°F (200°C).

  3. Froth with flour and butter.

  4. Serve on a very hot dish with a sauce made from cul'lis, fresh butter, ketchup, and red port boiled together.

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

What each ingredient does

Ox heart
Forms the main body of the dish, cooked whole and served sliced.
Veal caul
Wraps the heart to hold the stuffing in and keep the outside moist during roasting.
Butter
Froths over the heart and enriches the sauce, adding richness and a golden finish.
Red port
Adds sweetness and depth of flavour to the boiled sauce as it reduces.
Ketchup
Adds tangy sweetness and acidity to the sauce.

The step that matters

Increase the heat five minutes before it's done. A short blast of higher heat near the end browns the outside and sets the surface. Overcooking at high heat, though, dries the meat, so the timing needs care.
