Beurre Maître d'Hôtel is the archetypal compound butter of French cuisine — softened butter beaten with finely chopped parsley, lemon juice, salt, and white pepper, then rolled into a log and chilled for slicing into coins that melt languorously over grilled meats, fish, and vegetables. Named for the maître d'hôtel (head waiter) of grand dining rooms who would present it tableside, this preparation is simultaneously the simplest and most versatile of all compound butters, and understanding its technique unlocks the entire family. The method requires impeccable ingredients: use the finest unsalted butter at cool room temperature (15-16°C) — warm enough to be pliable but not soft or greasy. Work it with a spatula or wooden spoon until smooth and creamy, then incorporate very finely chopped flat-leaf parsley (squeeze it in a cloth first to remove moisture), freshly squeezed lemon juice (add gradually — too much at once will cause the emulsion to break), fine salt, and a pinch of white pepper. The ratios are 250g butter, 30g parsley, juice of half a lemon, and seasoning to taste. The parsley must be cut, not bruised — a sharp knife produces clean green flecks, while a dull blade crushes the cells and creates dark, oxidised smears. Mix until evenly distributed but do not overwork — the butter should remain creamy, not oily. Roll tightly in cling film or parchment into a uniform cylinder about 3cm in diameter, twist the ends, and chill until firm. Slice into 1cm coins just before service. Place atop a steak, a grilled sole, or roasted asparagus and watch it pool into an instant, elemental sauce — the heat of the food releases the butter's richness, the lemon lifts, the parsley provides colour and freshness. This is the foundation from which all classical compound butters derive.
Butter at 15-16°C — pliable but not warm or greasy. Parsley chopped very fine with a sharp knife, squeezed dry. Lemon juice added gradually to prevent emulsion breaking. Roll into tight cylinder 3cm diameter, chill until firm. Slice 1cm coins, serve immediately on hot food.
Make compound butter in large batches and freeze — it keeps for 3 months and you'll always have an instant sauce. Score the coins with a fork before serving for an elegant presentation. For an extra-silky texture, pass the finished butter through a drum sieve. The same technique applies to all compound butters — only the flavourings change. A touch of Dijon mustard (1 tsp per 250g) adds subtle complexity without being identifiable.
Using melted or overly soft butter, producing a greasy rather than creamy texture. Bruising parsley with a dull knife, creating dark oxidised specks. Adding too much lemon at once, breaking the emulsion. Not chilling long enough — butter coins should hold their shape. Forgetting to squeeze moisture from the parsley, which creates soggy pockets.
