Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Provide the bulk and firm body of the salad.
- Cooked mayonnaise
- Adds fat and moisture that coat and bind the salad together.
- Eggs
- Add richness and a soft, crumbly texture.
- Sardines
- Supply a savory, oily flavour that stands out in the salad.
- Onions
- Add a sharp aroma and a bite that balances the rich dressing.
- Cucumber
- Adds crisp texture and freshness through its moisture.
The step that matters
Mix all ingredients with the cooked mayonnaise.. Fold gently so the potato cubes and eggs keep their shape. Overworking breaks them down into a mush, and the mayonnaise should coat the pieces evenly so every bite is dressed.
