The choice of sauce contributes directly to the success of a caviar or smoked salmon tasting. Too strong, and it overwhelms the finesse of the main product. Too neutral, and it brings nothing to the experience. The right balance lies in sauces designed for the product they accompany. The house of Balik, for instance, created its dill mustard sauce specifically for its gravlax, in perfect aromatic harmony with the Scandinavian cure.
Crème fraîche remains the timeless classic for caviar and blinis, in a register of smoothness and elegant neutrality. Smetana, tangier, brings a more pronounced dimension, inherited from Slavic cuisines where it traditionally accompanies blinis and smoked salmon. Beyond the choice of sauce, it is the quantity that counts: better a light touch than an excess that masks the product.
