Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Vegetable Soup
Ingredients
Directions
Make the broth
Place the beef in a pot with 8 quarts of cold water and bring to a gentle boil.
Skim the surface carefully and add a little cold water two or three times to remove scum.
Add your choice of small-cut vegetables and cook moderately for 3 hours.
Brown the meat and serve
Remove the meat and place it in the oven to brown, basting with butter and water.
Strain the soup if you prefer it clear and serve with square bits of fried or toasted bread.
Add ½ cup of separately cooked rice before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef
- Releases flavor and gelatin into the broth while simmering, giving body to the soup.
- Vegetables
- Add sweetness, aroma and body to the broth as they cook.
- Cooked rice
- Adds bulk and a soft, starchy texture to the finished soup.
The step that matters
Skimming the surface. Scum rises as the water heats and can cloud the broth and taste bitter. Removing it carefully and adding small amounts of cold water keeps the broth clear and clean-tasting.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
