Soak seeds overnight (8–12 hours), drain, then dry really well
Roast at 170°C / 340°F for 15-20 minutes until fragrant
Blend with salt until creamy; add 1–2 tsp oil only if it needs help turning smooth
Give it a long blend in a food processor for about 10–15 minutes, blending in stages and pausing occasionally to scrape down the sides and give the machine a short break
