Ox Heart Stewed

Ingredients

Directions

Make the stew

  1. Place the ox heart pieces in a stew pot with salt and enough liquid to cover them. Skim off any scum that rises to the surface.

  2. Add the chopped onions, celery, and parboiled potatoes. Let the mixture stew gently until all ingredients are tender.

Thicken and serve

  1. About 15 minutes before serving, mix the butter, flour, and ketchup or walnut pickles together. Stir this mixture into the stew to thicken it.

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

What each ingredient does

Ox heart
Provides the main meat, which becomes tender through long, gentle stewing.
All-purpose flour
Thickens the stew's liquid when combined with butter and stirred in.
Butter
Adds richness and helps the flour blend smoothly into the stew.
Potatoes
Soften during stewing and add body to the broth.
Onions
Break down while stewing, adding sweetness and depth to the broth.

The step that matters

Stirring in the butter and flour mixture. Flour thickens best when it is blended with fat first and stirred in while the liquid is hot, which helps prevent lumps. Adding it too early or dropping it in unmixed can leave the stew clumpy or thin.

Swap the celery

How well each one fits the dish's main ingredients (meat, onion, potato, butter, flour, ketchup):

  1. Capersfits better
  2. Garlicfits better
  3. Thymefits about as well
  4. Celerythe original

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