Compound butter is softened butter mixed with flavouring ingredients such as herbs, garlic, shallots, spices, citrus zest, anchovies or wine reduction. It is shaped and chilled so it can be sliced or portioned, then used to finish hot foods, enrich sauces or add flavour to vegetables and seafood. In French cuisine it is called beurre composé.
A slice can be placed on a hot steak, grilled fish, vegetables or corn. As it melts, it creates a flavoured finishing sauce. Compound butter can also be used to enrich pan sauces and dressings.
Compound butter is whole butter mixed with flavourings. Clarified butter has had most of its water and milk solids separated from the butterfat. They serve different culinary purposes.
Chef’s tip: Portion compound butter before service and keep it chilled. Clearly label allergens and ingredients, especially when using dairy, fish, shellfish or other allergenic additions.
Key distinction: Compound butter is a flavoured butter preparation used as a condiment or finishing ingredient; it is not simply melted butter with herbs stirred in at the last moment.
