Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Raclette cheese
- Melts into a creamy, fluid sauce that coats the potatoes and onions.
- New potatoes
- Starchy body that holds its shape and soaks up the melted cheese.
- Pickled pearl onions
- Acidity that cuts through the richness of the melted cheese.
- French cornichons
- Sharp, acidic crunch that balances the fat of the cheese.
- Crusty french bread
- Sturdy, crisp vehicle for scooping up melted cheese.
The step that matters
Heat the cheese until thoroughly melted. Heating raclette gently until it is just fluid keeps it smooth and creamy. Overheating makes the fat separate, leaving the cheese oily and grainy.
Swap the onion
How well each one fits the dish's main ingredients (cheese, potato, bread):
- Tomatofits better
- Asparagusfits about as well
- Mustardfits about as well
- Onionthe original
Fit is the average pairing score against cheese, potato, bread. Candidates are from the same food group and used in at least 100 recipes.
