Step 1

Preheat oven to 350F (180C).

Step 2

Make pistachio paste: peel the pistachios from the shell. Roast the pistachios for 7-8 minutes (optional), then place them in a clean kitchen towel and shake to remove as much skin as possible.

Step 3

Place the pistachios in a powerful blender and blend until smooth and creamy. This process may take 10-15 minutes (depending on your blender) so be patient.

Step 4

Transfer the paste into a jar and keep it in the fridge.
