Prepare Your Workspace: Ensure all equipment is clean and dry. Moisture affects final texture.
Initial Processing Phase: Add pistachios to a food processor. Process on high speed, stopping every 2–3 minutes to scrape down the sides. Continue for about 8–10 minutes until a coarse meal forms.
Oil Release and Smoothing: Continue processing. Natural oils will release and begin forming a paste. This occurs around 12–15 minutes. Do not add oil prematurely.
Final Texture Adjustment: Once creamy and smooth, add oil if needed. Process an additional 2–3 minutes. Optional: add a pinch of salt.
Quality Check and Storage: Transfer to an airtight jar. Store refrigerated for up to 1 month or frozen for 3 months.
