Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Browning in hot oil builds deep, sweet, savory flavor that carries through the dip.
- Olive oil
- Carries the heat to brown the onions and adds fat that rounds out the flavor.
- Sour cream
- Provides the creamy, tangy base that gives the dip its body and moisture.
The step that matters
Fry the onions until deep brown. Onions need enough time in hot oil for their sugars to caramelize and develop sweetness and color. Stopping early leaves a raw, sharp taste that the cool sour cream will not mellow.
