Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef marrow
- Melts when heated, giving the toast a rich, buttery fat that coats the bread.
- Lemon juice
- Adds acidity that cuts through the richness of the marrow.
- Bread
- Provides a crisp, toasted base that holds the warm marrow.
- Parsley
- Adds fresh, herbal aroma to the rich marrow.
The step that matters
Boil the marrow for 1 minute. Boiling briefly firms the marrow and removes some surface blood and loose fat, so the heated topping stays clean and less greasy. Overcooking would melt it away from the bread.
