What each ingredient does

Truffles
Provide the main earthy, aromatic flavour of the ragout.
Butter
Adds fat for richness and a smooth, glossy texture to the sauce.
White wine
Adds acidity and brightness that balances the rich, savoury sauce.
Reduced espagnole sauce
Adds savoury depth and body to the ragout.

The step that matters

Let the truffles sweat over low heat. Gentle heat slowly releases the truffles' aroma into the butter without browning or toughening them. High heat can scorch the butter and dull the delicate flavour.
