Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Releases savory flavor and body into the broth as it slowly simmers.
- Pearl barley
- Thickens the broth and becomes tender and chewy as it absorbs liquid.
- Onions
- Add sweetness and aroma as they soften and melt into the broth.
- Potatoes
- Add starch that gives the broth more body and softens into the liquid.
The step that matters
Keep the broth at a steady simmer, not a boil. Boiling toughens the beef, breaks up the potatoes, and makes the broth cloudy. Stirring often keeps the barley and starches from settling and scorching on the bottom of the pot.
Swap the onion
How well each one fits the dish's main ingredients (beef, barley, parsley, potato, thyme, pepper):
