Smoked Salmon Butter

Beurre de saumon fumé (smoked salmon butter) teaches the strictest rule of a beurre composé, a flavored butter: balance comes from weight, texture from temperature. There is no pan to touch. Before the blade moves, know this: the salmon and butter must be equal by weight, and the butter must be cool and pliable, never hard and never greasy.

The original assumes none of the usual grand-kitchen apparatus, no saucier, no stockpot kept at the fire, no salamander. It assumes a mortar, a strong arm, and a fine sieve. A small food processor honestly replaces the pounding labor for one cook, while the sieve stays because it isn't brigade scaffolding. It is the dish. The book's four ounces of salmon and four ounces of butter already make a sensible home batch, so I keep that measure exactly rather than inflating it for service. One cook, one stove, one evening.

The finished beurre de saumon fumé should be pale rose, satin-smooth, and clean on the tongue, with butter rounding the smoke rather than muffling it. We don't apologize for butter; here it is half the recipe and exactly the point. The final passage through the sieve is the step that matters most, so don't let the processor flatter you into skipping it.
