Lemon myrtle butter

Backhousia citriodora · A flavoured compound butter in which softened butter is creamed with dried lemon myrtle leaf (Backhousia citriodora) — the intensely 'lemonier-than-lemon' Australian native herb — and salt, then shaped and chilled for later use as a finishing or pan-basting fat.

Ingredients

Fatunsalted butter, softened to room temperatureSoftened (not melted) butter traps the leaf oils in an emulsion rather than letting them pool.
Flavordried lemon myrtle leaf (Backhousia citriodora)Whole, broken or finely ground; the principal source of citral aroma.
Seasoningfine saltSharpens the citrus oils and stabilises the emulsion.

Method

  1. 1Soften butter to a pliable, room-temperature consistency (about 18–20 °C).A soft-but-not-melted fat will fold with aromatics without splitting or weeping.
  2. 2Crush or finely rub the dried lemon myrtle leaves to bruise the leaf tissue.Bruising ruptures the oil glands so citral is released into the butter rather than left locked inside leaf fragments.
  3. 3Combine butter, bruised lemon myrtle and salt in a bowl and mix thoroughly with a spatula or wooden spoon until evenly coloured and flecked.Uniform distribution ensures every slice or spoonful delivers the same citrus hit.
  4. 4Taste, adjust salt and lemon myrtle, then rest the butter for 10–15 minutes to allow the aromatics to infuse.A short rest lets the fat-soluble citral migrate through the butter for a rounder, more cohesive flavour.
  5. 5Spoon onto plastic wrap, roll into a log, twist the ends and chill until firm.A chilled log can be portioned into neat coin-sized discs for service and melts controllably in a hot pan.
  6. 6Slice coin-off as needed for finishing fish, vegetables or for mounting a reduced jus.Cold discs melt in a controlled swirl, baste evenly and do not slough off into the sauce.

Techniques that matter

Compound butter (beurre composé)

The standard French base technique for capturing herbs, spices and aromatics in a reusable fat that is reshaped and chilled for later portioning.

Beurre monté / mounting with cold butter

Cherikoff's butter-sauce method whisks cold flavoured butter into a hot reduced stock off the heat to emulsify and gloss the sauce without breaking.

Variations & derivatives

Lemon myrtle, garlic and lemon-zest butterAustralia (quitelike.com)

Adds finely grated garlic and lemon zest to the base butter for a more layered citrus-and-allium profile used to baste pan-fried fish.

Lemon myrtle sprinkle butter sauceAustralia (Cherikoff)

Replaces the leaves with Lemon Myrtle Sprinkle at 5 g per litre of reduced jus (0.5%), infused 30 seconds, then finished off the heat with cold butter to emulsify.

Substitutions

  • Dried lemon myrtle leaf → Lemon zest (1–2 tsp) plus a pinch of ground lemon myrtle — Zest alone lacks lemon myrtle's sweet-spicy depth; blend with a little dried leaf for fidelity.
  • Dried lemon myrtle leaf → Kaffir lime leaf, makrut leaf — Provides citrus aroma but a more floral, peppery profile — not a clean swap.changes result
  • Unsalted butter → Clarified butter or ghee — Allows higher-heat basting without milk solids burning; mild loss of creamy mouthfeel.

Troubleshooting

Butter tastes bitter or astringent

Leaves were over-crushed, releasing excess tannins and chlorophyll; or butter was left to infuse too long in heat. → Use gentler bruising or whole-leaf infusion, shorten the rest time, and discard very finely powdered material.

Weak or one-dimensional citrus flavour

Insufficient leaf relative to butter, or insufficient resting time for citral to migrate into the fat. → Increase dried leaf to 2–3 tsp per 100 g and rest the mixed butter 15–30 minutes (or overnight, chilled) before firming.

Grainy, split or weeping texture

Butter was too cold to emulsify, or was warmed until it melted and resolidified unevenly. → Always work with truly room-temperature butter; re-melt, cool and re-set only if fully melted by accident.

Flavour fades on hot applications

Citral and other lemon myrtle volatiles flash off when the butter is added too early or over direct high heat. →

Storage

Keeps 2–3 weeks refrigerated; up to 3 months frozen — Roll tightly in plastic wrap or seal in an airtight jar; for longer keeps, freeze the log whole and slice from frozen. Reheat: Slice from chilled or frozen log directly into a hot pan or warm sauce — no need to soften first; a little melt then re-firm is fine for spreading.
