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

What each ingredient does

Kale
Becomes tender while cooking down, forming the bulk of the filling.
Garlic
Softens in the oil and adds a savory, aromatic base to the filling.
Kalamata olives
Add salty, briny flavor that seasons the kale mixture.
Capers
Contribute briny, tangy acidity that balances the rich olive oil.
Extra-virgin olive oil
Carries flavor and coats the kale, adding fat and moisture to the filling.

The step that matters

Cover and cook the kale mixture. Cooking covered for 15 to 20 minutes with occasional stirring lets the kale soften and release moisture. Stirring helps the mixture cook evenly so pieces don't scorch on the bottom of the pan.

Swap the clove
