Name: Chicken Soup with Fennel and Spinach
Ingredients: 1 tablespoon olive oil; 2 fennel bulbs, coarsely chopped (4 cups), fronds and shoots reserved for garnish; 1/2 teaspoon salt; 1/4 teaspoon freshly ground pepper; 1 small shallot, chopped; 4 (14-1/2 ounce) cans reduced-sodium chicken broth; 2 chicken legs (thigh and drumstick), skin removed; 1 (10-ounce) bag of fresh spinach; 2 teaspoons freshly grated lemon zest

Why it works: Fennel and lemon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 723 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓

Chicken Soup with Fennel and Spinach

Timeabout 20 minutes

Ingredients

1 tablespoon olive oil
2 fennel bulbs, coarsely chopped (4 cups), fronds and shoots reserved for garnish
1/2 teaspoon salt
1/4 teaspoon freshly ground pepper
1 small shallot, chopped
4 (14-1/2 ounce) cans reduced-sodium chicken broth
2 chicken legs (thigh and drumstick), skin removed
1 (10-ounce) bag of fresh spinach
2 teaspoons freshly grated lemon zest

Directions

Prepare the vegetables

Heat oil in a large pot over medium heat until it shimmers.
Add fennel and cook 10 minutes, stirring occasionally, until it begins to brown.
Add salt, pepper, and shallot; cook 5 minutes, stirring occasionally, until the shallot is softened and the fennel is lightly browned.

Simmer the chicken

Add chicken broth and chicken legs, bring to a boil over medium-high heat.
Reduce heat to low, cover, and simmer until the chicken is cooked through, about 20 minutes.
Remove the pot from heat and transfer the chicken to a colander.
Run the chicken under cold water until it is cool enough to handle.
Remove the meat from the bones, shred it, and add it to the soup.

Finish and serve

Stir in spinach and lemon zest.
Spoon the soup into serving bowls and garnish with reserved fennel fronds and shoots, if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Fennel bulbs: Softens and browns when cooked, adding sweetness and a mild aniseed aroma to the broth.
Chicken legs: Release flavor and gelatin into the broth while cooking, and provide the soup's main meat.
Chicken broth: Forms the liquid base of the soup and carries the flavors of the other ingredients.
Spinach: Wilts quickly in the hot soup, adding color, body and a green, leafy flavor.
Shallot: Softens into the oil, adding a mild sweet onion-like savoriness to the base.

The step that matters

Browning the fennel. Cooking the fennel until it begins to brown lets its sugars caramelize, building deeper flavor. Pale, underbrowned fennel leaves the soup tasting flat and raw.
