Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Barley Soup
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
In a stone jar, combine the stock and barley.
Add the dripping, salt, pepper, and herbs.
Cover and place the jar in a slow oven at 300°F (150°C) for about three hours.
After an hour, add the grated carrot, fried onion, mushroom ketchup, and chopped celery.
Adjust the seasoning with additional flavorings like vinegar, garlic, or curry as desired.
You may also add scraps of meat if available.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley
- Thickens the soup as it cooks and gives it a chewy, hearty texture.
- Stock
- Forms the liquid base that the barley cooks in and carries the flavour.
- Dripping
- Adds fat for richness and a rounder, savoury mouthfeel.
- Onion
- Adds savoury sweetness and aroma as it softens during the long cook.
