Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Milk
- Forms the creamy liquid base that carries the avocado and tarragon flavors.
- Avocados
- Provide the body, richness and smooth texture of the bisque.
- Lemon juice
- Adds acidity that brightens the flavor and helps slow browning of the avocado.
- Tarragon leaves
- Infuse the milk with their aromatic, anise-like flavor.
The step that matters
Heat the milk without boiling. Bringing the milk only to a simmer keeps it from scalding and curdling, so it stays smooth and blends evenly with the avocado purée.
