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 other flavors.
Avocado
Provides richness and a smooth, velvety body from its natural fats.
Tarragon
Adds a sharp, anise-like aroma that flavors the milk.
Lemon juice
Adds acidity that brightens the flavor and helps keep avocado from browning.

The step that matters

Heat the milk without boiling. Milk that boils can scorch on the bottom and form a skin or curdle, so heating only until it just begins to simmer keeps the base smooth and tarragon flavor clean.
