Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Avocados
- Provide creamy, fatty body and moisture to the sandwich filling.
- Dijon mustard
- Adds sharp, tangy flavor and helps emulsify the spread.
- Mayonnaise
- Adds fat and richness, giving the spread a smooth, creamy texture.
- Lemon juice
- Adds acidity that brightens flavor and slows browning of cut avocado.
- Tomatoes
- Contribute juiciness and acidity that moisten and balance the sandwich.
- Sourdough bread
- Gives a sturdy, chewy structure that holds the moist filling.
The step that matters
Serve immediately. Cut avocado oxidizes and turns brown when exposed to air, and assembled bread softens as moisture from the tomato spreads, so the sandwich is best eaten soon after it is built.
Swap the arugula
