I’ve experimented with lots of different nuts, seeds and fruit in bliss balls and I’ve finally hit on a winner! The key ingredient is sunflower seeds. There’s something about their flavour and creamy texture when blitzed into a butter that makes other contenders pale in comparison. And blitzing them into a butter on their own first is indeed vital if you want lovely smooth, fudgy balls. Bonus for those with nut allergies, too!
