Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Pearl barley
- Swells during long simmering, thickening the broth and giving it body.
- Turnips
- Soften during simmering and, rubbed through a sieve, add body and mild sweetness.
- Onions
- Break down during the long simmer, adding savoury depth and sweetness to the broth.
- Milk
- Adds richness and a smoother, creamier mouthfeel to the finished broth.
The step that matters
Boil for 2 to 2½ hours. Barley and root vegetables need a long, steady simmer to become fully tender and to release starch that thickens the broth. Too little time leaves the barley firm and the broth thin. A rolling boil can also break the vegetables apart unevenly, so keep the liquid at a gentle, steady boil.
Swap the onion
