Understanding the Context

The 3 Core Ingredients You Need

Mayonnaise (The Creamy Base)
The foundation of any classic tartar sauce, mayonnaise provides a rich, velvety texture that binds all the flavors together. Choose a high-quality, neutral-tasting mayo for versatility — it won’t overpower the delicate taste of seafood while balancing richness.
Lemon Juice (The Bright, Zesty Kick)
Freshly squeezed lemon juice is what brings tartness and lift. It cuts through the creaminess of mayo, adds vibrancy, and enhances the natural oceanic flavors of fish and shellfish. Avoid bottled lemon juice — fresh juice gives that bright, alive zing.
