What each ingredient does

Beef
Provides the main savoury meat flavour and, from its bones, body to the liquid.
Veal knuckle
Its bones and connective tissue release gelatin during simmering, giving the sauce body and mouthfeel.

The step that matters

Skimming off the foam at the boil. Foam carries coagulated proteins and impurities that would cloud the liquid and can taste bitter. Removing it early keeps the stock clear and clean-flavoured.
