Marrow Toast
Ingredients
Directions
Prepare the marrow
Saw beef bones into short pieces and cover ends with a flour and water paste.
Boil the bones in a floured cloth for about 2 hours.
Remove the marrow from the bones and season with pepper and coarse sea salt.
Assemble and serve
Spread the seasoned marrow on fried bread or hot buttered toast cut into fancy shapes.
Place in the oven until hot and serve immediately.
Sprinkle with chopped parsley and add a dash of lemon juice before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef bones
- Provide the rich marrow that forms the dish's main body and flavour.
- Lemon juice
- Adds acidity that brightens the rich, fatty marrow.
The step that matters
Boil the bones in a floured cloth for about 2 hours. Marrow must be heated long enough to soften and loosen from the bone without the bone breaking apart. Sealing the ends with flour paste and wrapping in a floured cloth helps protect the bones and keeps the marrow from leaking out during cooking.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
