Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Cheap Barley Broth
Ingredients
Directions
Prepare the broth
In a large pot, bring 6 quarts of water to a boil.
Add 6 ounces of Scotch barley and the peeled onions.
Optionally, add chopped turnips and carrots.
Boil for 1.5 hours, then strain the mixture.
Thicken and finish
In the hot pot, melt 2 to 3 ounces of dripping or pot‑top.
Stir in ¼ pound of oatmeal until it forms a smooth paste.
Gradually return the strained barley, water, and onions to the pot, stirring well.
Add parsley, marigold blossoms, and ground pepper.
Boil for an additional 15 to 20 minutes.
Stir in 3 teaspoons of salt and serve.
If the broth is too thick, stir in a little cold milk.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Scotch barley
- Releases starch and body into the water during the long boil, thickening the broth.
- Oatmeal
- Forms a smooth paste with the melted fat that thickens the broth further.
- Onions
- Add sweetness and savory depth as they simmer in the broth.
- Dripping or pot-top
- Adds fat and richness, carrying flavour and giving the paste its smooth body.
The step that matters
Stirring the oatmeal and fat into a smooth paste. If the oatmeal is added without first blending it thoroughly with the melted fat, lumps form that do not disperse later. Working the paste smooth before adding the liquid lets the starch hydrate evenly and thicken the broth uniformly.
