Why it works: Olive and garlic are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 25,665 recipes. Both carry linalool, which smells floral, citrus. The science ↓
Black Olives with Harissa
Ingredients
Directions
Prepare the olives
Rinse olives under cold water for 1 minute in a colander.
Place olives in a large bowl and cover with cold water.
Soak olives for 4 hours to remove excess salt, then drain well.
Roast the pepper
Using a long‑handled fork, char peppers over an open flame or on a rack set over an electric burner, turning, until skins are blackened, 4 to 6 minutes; or broil peppers on a broiler pan about 2 inches from heat, turning every 5 minutes, until skins are blistered and charred.
Transfer peppers to a bowl and let stand, covered, until cool enough to handle.
Peel peppers, starting at blossom end, keeping peppers whole.
Cut off pepper tops and discard seeds and ribs.
Make the harissa
Grind cumin, coriander, and caraway seeds finely in a mortar with pestle, electric spice grinder, or cleaned coffee grinder.
If using mortar and pestle, add chilies, garlic, and salt, then pound to taste.
If using a grinder, transfer seeds to a small food processor, add chilies, garlic, and salt, then grind to a paste.
Add roasted pepper and olive oil, then pound or purée to a coarse paste.
Marinate and serve
Stir together harissa and olives in a large bowl.
Marinate covered and chilled for at least 6 hours or overnight.
Prepare olives up to 1 week ahead, keeping chilled and covered.
Serve olives at room temperature.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Oil-cured black olives
- Provide the main flavor and salty, meaty texture that the harissa seasons.
- Hot red dried chilies
- Supply heat and a smoky, fruity chili flavor to the harissa.
- Garlic cloves
- Add pungent, savory aroma that deepens the paste.
- Red bell pepper
- Adds sweetness, body and moisture to the coarse paste.
- Olive oil
- Carries the spice flavors and gives the paste a smooth, rich fat.
The step that matters
Soaking the olives. Soaking for the full 4 hours draws out excess salt from the cured olives; skipping or shortening it leaves the marinated olives too salty.
