Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Rabbits
Provide the main protein, which roasting cooks until tender and browned on the outside.
Onions
Brown slowly to build a sweet, deep flavor that gives the sauce its color and body.
Butter
Carries the onions as they cook and adds richness and a glossy finish to the sauce.
Espagnole sauce
Forms the base of the sauce, adding body and savory depth when reduced.
Lemon juice
Adds acidity that brightens the rich, heavy flavors of the sauce.

The step that matters

Stir the onions until fine brown. Onions cooked slowly over medium heat caramelize gradually and turn sweet and deep in color. Rushing with high heat can scorch them and leave a bitter taste that carries into the sauce.

Swap the lemon
