Frozen Beef Marrow Bones

Beef marrow bones are prized two ways. Roasted, the marrow softens to a rich, buttery spread: roast at 220C for 15 to 20 minutes until it is soft and beginning to bubble, then scoop it onto toast with salt and parsley. Simmered, they are the backbone of a proper bone broth: roast the bones first for depth, then simmer for 12 to 24 hours with a splash of vinegar to draw out the minerals, producing a collagen-rich broth that gels when cold. The marrow itself is energy-dense and rich in healthy fats.

 They also add body to stocks, soups and sauces. 'Halal bone marrow' has the highest click-through rate of any search term on the site, so this is a genuinely in-demand product.
