Prepare the meat
Have the butcher saw the shin bone into 2-inch pieces.
Wash the meat in cold water.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shin of beef
- Slow simmering breaks down connective tissue and bone, giving the broth body and rich flavour.
- Pearl barley
- Its starch thickens the broth slightly and adds a chewy texture.
- Potatoes
- Starch softens during simmering, adding body and making the soup more filling.
- Wheat flour
- Stirred into water and added at the end, it thickens the broth into a smoother consistency.
The step that matters
Stirring in the flour thickening gradually. Flour clumps if dumped in at once. Mixing it with water first and adding it slowly while stirring lets the starch disperse and thicken the broth evenly.
Swap the potato
