Why it works: Carrot and pepper match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 14,555 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Baked Soup
Ingredients
Directions
The book says “a rather slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Wash the rice and split peas.
Place them in a pot with the vegetables and meat.
Season with salt and pepper, then add the cold water.
Bake and serve
Cover the pot tightly and cook in a slow oven at 300°F (150°C) for 3 to 4 hours.
Skim the surface, then transfer the soup to a tureen and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Split peas
- Break down during long cooking to thicken the soup and give it body.
- Lean beef or mutton
- Adds savory meat flavor and protein to the broth as it cooks slowly.
- Rice
- Adds body and helps thicken the soup as its starch releases during cooking.
- Onion
- Contributes sweetness and aromatic depth to the broth as it softens.
The step that matters
Cover the pot tightly and bake low and slow. A tight lid keeps liquid from evaporating, and gentle heat over several hours lets the split peas and meat soften fully without scorching or drying out.
Swap the peas
How well each one fits the dish's main ingredients (beef, rice, onion, carrot, pepper):
- Beansfits better
