Notes
- Compound Butter Texture: This is a firm compound butter, not a loose lemon butter sauce. The lemon juice is reduced briefly so the finished butter stays sliceable.
- Dry the Capers Well: Capers carry brine. Rinsing, draining, patting dry, and chopping them helps prevent watery pockets in the butter.
- Cool Before Mixing: Warm caper-shallot base will melt the butter and ruin the texture. Let it cool completely.
- Lemon Balance: Lemon zest gives the strongest clean citrus flavor without adding liquid. Use extra zest before adding more juice.
- Dill and Seafood: Dill keeps this butter especially good for salmon, white fish, shrimp, crab, scallops, and lobster.
- Dijon Mustard: A small amount gives the butter body and a quiet sauce-like sharpness without making it taste like mustard.
- Using as a Sauce: For dipping lobster, crab, clams, or shrimp, melt the finished compound butter gently over low heat. Do not boil it hard or the butter can separate.
- Storage: Store refrigerated in an airtight container for up to 1 week, or freeze the wrapped log for up to 3 months.
- Serving Suggestions: Serve with lobster tails, steamed clams, shrimp skewers, crab legs, seared scallops, oysters, grilled salmon, baked cod, halibut, roasted asparagus, baked potatoes, corn on the cob, or warm dinner rolls.
