Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shad roes
- Provides the rich, delicate flavor and the mashed body of the sauce.
- White sauce
- Supplies a creamy base that carries the mashed roe and gives the sauce its smooth texture.
- Lemon juice
- Adds acidity that brightens the rich, fatty roe and balances the sauce.
The step that matters
Cover and simmer gently, do not boil hard. Roe is delicate, and high heat firms and toughens its proteins and can break the sacs apart. A gentle simmer cooks it through while keeping it tender enough to mash smoothly.
