Gravy Kettle

Ingredients

Directions

Make the glaze

  1. Pour a small quantity of liquid into the pan and reduce it by rapid boiling until it becomes a glaze.

  2. Once the glaze has the proper color, add boiling broth in small portions and shake the pan to detach the glaze.

Stew

  1. Stew the meat gently for 3-4 hours with mushrooms, parsley, and green onions or a Portugal onion.

  2. Add thick slices of unboiled ham for richer flavor.

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

What each ingredient does

Unboiled ham
Adds meaty, savory flavor to the broth during the long stew.
Mushrooms
Contribute earthy flavor and moisture to the stew.
Boiling broth
Provides the liquid base and dissolves the glaze into the sauce.
Green onions or portugal onion
Add aromatic sweetness and depth as they soften in the stew.

The step that matters

Reducing the liquid to a glaze. Rapid boiling concentrates the liquid and caramelizes its sugars and proteins into a browned glaze. If it is under-reduced or burnt, the flavor is weak or bitter. Adding broth too quickly can stop the glaze from detaching cleanly.

Swap the parsley

How well each one fits the dish's main ingredients (mushroom, onion, ham):

  1. Garlicfits better
  2. Thymefits better
  3. Celeryfits better
  4. Parsleythe original

Fit is the average pairing score against mushroom, onion, ham. Candidates are from the same food group and used in at least 100 recipes.
