Optional roasting: Spread the pistachios on a baking sheet and roast for 7–8 minutes, just until fragrant. Let cool completely.
Remove skins (optional but recommended): Transfer warm pistachios to a clean kitchen towel, rub gently to loosen and remove as much skin as possible. Read notes.
Blend: Place the pistachios in a powerful food processor or high-speed blender. Blend until smooth and creamy, stopping to scrape down the sides as needed.
The mixture will go from crumbs → thick paste → smooth butter.
This can take 5–15 minutes, depending on your machine. Be patient.
Store: Transfer the pistachio paste to an airtight jar. Refrigerate until ready to use

Notes
Minimum quantity matters: Use at least 300–400 g pistachios. Smaller amounts often won’t release enough oil to turn into a smooth paste.
Roasted vs raw pistachios: Roasting adds deeper, nuttier flavor but slightly darkens the color. For the brightest green paste, skip roasting or blanch and peel the pistachios.
Oil: Pistachios contain enough fat on their own. If needed, add 1–2 tablespoons neutral oilonly after the paste has formed to improve smoothness.
Storage:
Refrigerator: Airtight container for 2–3 weeks (stir before use if oils separate).
Freezer: Freeze for up to 3 months. Thaw overnight in the fridge and stir well.
