Why it works: Tomato and celery are a kitchen classic. They rank in the top 4% of all ingredient pairs, and cooks put them together in 3,377 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

What each ingredient does
- Soup bone
- Slow simmering draws flavor and gelatin from the bone, giving the broth body and depth.
- Tomatoes
- Add acidity and fresh, bright flavor that balances the rich broth.
- Tapioca
- Its starch swells and thickens the soup as it boils, becoming clear and giving a light body.
The step that matters
Boiling the tapioca after it is added. Tapioca starch must boil long enough for its granules to swell fully and gelatinize. Under-boiled starch stays chalky in taste and texture and fails to thicken the soup properly.
