Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Cucumbers
Provide the main crisp, fresh body of the salad.
Green tomatoes
Add tart, acidic flavor and firm texture to the chopped mixture.
Cabbage
Adds crunch and bulk that holds up after the salad is pressed.
Onions
Contribute sharp aroma and savory flavor throughout the salad.

The step that matters

Pressing out the water. Cucumbers, tomatoes, and cabbage release a lot of liquid. Draining and pressing removes it, so the salad stays crisp rather than watery and diluted.

Swap the clove
