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 ↓
Chicken a LA Marengo

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Rooster
- Provides the main protein, which firms as it cooks and browns for flavor.
- White wine
- Adds acidity and aroma that balance the rich chicken.
- Tomatoes
- Add acidity and liquid that help form the sauce as it simmers.
- Butter
- Adds fat and flavor, supporting rich browning on the chicken.
- Onion
- Adds aromatic sweetness as it softens into the sauce.
The step that matters
Browning the chicken well. Deep browning creates Maillard flavors and color that the sauce builds on. If the pieces are crowded or wet, they steam instead of browning, leaving the dish pale and less flavorful.
Swap the clove
How well each one fits the dish's main ingredients (garlic, butter, egg, parsley, onion, wine, white wine):
- Thymefits better
- Tarragonfits better
- Capersfits better
- Clovethe original
Fit is the average pairing score against garlic, butter, egg, parsley, onion, wine, white wine. Candidates are from the same food group and used in at least 100 recipes.
