Simple toasted bread, blinis, cucumber slices, or pumpernickel bread are regularly used as a base that's spread with ingredients such as cheese, crème fraîche, or sour cream, while common flavorings include condiments and herbs such as lemon juice, lemon zest, horseradish, mustard, dill, and capers.
