Step 1

Preheat an oven to 350°F (175C/155C Fan) and spread the pistachios on a baking tray. Roast these lightly in the oven for about 8 minutes to help release their oils.

Step 2

Remove the pistachios from the oven and add to a foo processor along with 1½ tablespoons of honey.

Step 3

Blend in the food processor until nuts have broken down into a paste. To get a nice smooth paste, this will take time - about 25-30 minutes on high (dependent on your food processor). Stop the machine every 5 minutes to scrape down the sides and check progress, until you reach your desired consistency.

Step 4

Once you've achieved a spreadable paste, remove from the food processor and spoon into a bowl or jar.
