Compound butters are probably one of the first things we learn at trade school. Simply put, it is butter with flavourings. It’s used much like a sauce for many dishes like on roasted vegetables or to toss through freshly blanched beans, on roasted fish, cut into small discs and stuffed in between the skin and flesh of chickens ready for roasting for moisture and flavour and traditionally,it is used on grilled meats, mainly as a sauce or in corporation with a jus to monte the jus with more flavour.
