Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Bread
- Provides a soft, neutral base and structure to hold the caviar filling.
- Butter
- Adds richness and moisture, and keeps the bread from soaking up the filling.
- Caviar
- Supplies the salty, briny flavor and luxurious texture that define the sandwich.
- Lemon juice
- Adds acidity that brightens the rich butter and salty caviar.
The step that matters
Pressing the sandwiches together. Pressing too hard can crush the delicate caviar pearls and squeeze out the filling, while too light a press leaves the layers loose and slippery when cut. A gentle, even press keeps the eggs intact and the sandwich neatly bonded.
