Making Live Rosin Butter at Home
(the cleanest, terpiest cannabis butter you can make – full-spectrum flavor without solvents)
Live rosin (fresh-frozen bubble hash pressed with heat/pressure) is the gold standard for flavor and entourage effect. Infusing it into butter keeps all those delicate terpenes intact while giving you a potent, aromatic base for edibles.
What you need (for ~400–500 mg THC butter batch)
- 2–3 g premium live rosin (aim for 70–90% THC, fresh and terpy)
- 1 cup (226 g) unsalted European-style butter (Kerrygold preferred for richness)
- ½ tsp liquid sunflower lecithin (for even distribution and better bioavailability)
- Small mason jar + sous-vide setup (or double boiler)
The Low-Heat Method (preserves terpenes, maximum clarity)
1. Melt butter gently to 160–170 °F in small pot or jar.
2. Add lecithin → whisk until dissolved.
3. Crumble or scoop rosin into warm butter → stir gently until fully melted and homogeneous (rosin dissolves easily in fat).
4. Pour into mason jar → sous-vide at exactly 176–185 °F for 90–120 minutes (longer pulls more, but don’t exceed 190 °F or terps start to degrade).
5. No straining needed – rosin is solventless and leaves zero plant material.
6. Cool to room temp → fridge to solidify.
Results
- Potency: near 100% transfer (rosin is already activated)
- Flavor: bright, strain-specific terpenes shine through – citrus, pine, fruit, whatever your rosin profile is
- Texture: silky, spreadable, crystal-clear when melted
- Shelf life: 2–3 months fridge, 6+ months frozen
Dosing guide
- 2 g 80% rosin = ~1600 mg THC → 1 cup butter = ~1600 mg total
- 1 tbsp butter = ~100 mg (adjust based on your rosin lab numbers)
Pro tips
- Use light-colored rosin for neutral butter; darker for deeper flavor.
- For extra terp preservation: infuse at lowest temp (170 °F) for longer (3 hours).
- Best in recipes where flavor matters: brownies, blondies, frostings, toast.
- Freeze in ice cube trays for pre-portioned doses.
This is the butter that makes people say “these edibles taste like the strain.”
No chlorophyll, no harshness, just pure live rosin goodness.
Your press + this method = next-level kitchen game.
Worth every gram.
