Put Beef bones in a big pot, cover generously with cold Water and bring to a hard boil. Boil for 10 min, then drain and rinse every bone under the tap until no scum is left. Wash the pot out too: this is what keeps the finished broth clear instead of cloudy and grey.

⚠ Do not skip this. The first boil pulls out the blood and impurities that would otherwise muddy the broth.
