Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef bones
- Source of the marrow, which provides richness and a soft, fatty texture.
- Butter
- Adds fat and flavour to the toast and helps it brown lightly.
- Lemon juice
- Adds acidity that cuts through the richness of the marrow.
The step that matters
Bring the marrow to a boil over high heat, then drain. Brief high heat firms the diced marrow so it holds its shape on the toast. Prolonged heat would melt the fat out, leaving the pieces greasy and loose.
