Why it works: Garlic and onion match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 29,058 recipes. Both carry furaneol, which smells caramel, strawberry. The science ↓
Spicy Tomato Soup
Ingredients
Directions
Prepare
Finely chop 1 bunch of cilantro, removing tough stems.
Combine ground beef, eggs, rice, flour, salt, pepper, garlic powder, and cumin in a large bowl, mixing well.
Shape the mixture into meatballs about 1 1/2 inches in diameter.
Make the soup
Bring 2 1/2 quarts of water to a boil in a large stockpot over high heat.
Add the meatballs and 1/4 cup uncooked rice, and boil for 30 minutes, skimming off any scum that rises to the top.
Heat 2 tablespoons vegetable oil in a medium skillet over medium heat.
Add 2 sliced onions, 2 sliced tomatoes, and about one-sixth of the serrano chiles, and sauté until the onion is softened, about 5 minutes.
Add the onion mixture to the meatballs and broth, along with the remaining serrano chiles; reduce the heat to low and simmer for 10 minutes.
Just before serving, stir in the chopped cilantro.
Serve
Serve soup with warm corn tortillas and refried beans.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ground beef
- Forms the meatballs and provides the main body and savory flavor of the soup.
- Eggs
- Bind the meatball mixture so the meatballs hold their shape while boiling.
- Rice
- Adds bulk and softness to the meatballs and helps them stay tender.
- Flour
- Helps the meatballs hold moisture and keeps them from becoming dry or crumbly.
- Onions
- Soften and turn sweet when sautéed, adding depth to the broth.
- Tomatoes
- Add acidity and body to the broth as they cook down.
The step that matters
Boil the meatballs for 30 minutes and skim the scum. Scum rising from the meat and fat is mostly coagulated protein and fat. Skimming it keeps the broth clear and clean-tasting while the meatballs cook through in a steady boil.
Swap the onion
