Set the oven to 350°F / 180°C before you start, and spread the pistachios out flat on a tray.
02 -
Pop the pistachios into the oven for about 7 minutes. Jiggle the tray halfway so everything cooks evenly. Keep an eye (and nose) on them—they shouldn't get too dark or bitter. Once you smell that nutty aroma, they're good.
03 -
Take the tray out and leave the nuts to cool completely before blending.
04 -
Put the cooled pistachios into a food processor and blend them. The texture will change as you go—from chunks to a powder, then clumps, before finally forming a smooth buttery paste.
05 -
If the pistachios seem too crumbly and dry and aren't smoothing out, drizzle in a little oil to loosen it up.

Want it salted? Sprinkle in some salt and give it a quick blitz to mix. If not, scoop it right into a storage jar.
